I tried to install v.strahler and the included other scripts (v.mainchannel, r.broscoe, r.strahler) on a Mac OS X 10.8 with GRASS GIS 6.4.2 (from kyngchaos) and eventually succeeded, but the following errors were shown during the compilation of v.strahler:
ld: warning: directory not found for option '-L/usr/local/pgsql-9.0/lib'
ld: warning: directory not found for option '-L/usr/local/pgsql-9.0/lib'
ERROR: G_getenv(): Variable GISDBASE not set
I suspect that the module is not working properly, because I can not replicate output that was obtained with an older installation of GRASS GIS (6.3) and an older version of OS X (10.6). In the some project location and for the same maps used in the past, I now obtain a shapefile with 99% 0 i.e. no Strahler order assigned. In the past this worked much better, the old map shows only ~20% 0s (due to braided streams etc.). In addition, the Manual is not shown in the GUI window - but was in the past.
Could this be due to a wrong compilation that something is missing - or does the module not run properly anymore under newer versions of GRASS or OS X?
I actually, tried to install v.strahler via g.extension on a Windows XP machine as well, but although it said "Successfully installed", it gives an error message when calling the module in the GUI and says "unknown command" on the command line.
I am aware that the r.stream.order etc. exists, but I want to assign Strahler order to an existing stream network.

I have completely (hopefully) demessified the structure of v.strahler and
related tools. They are installed separately now which hopefully helps
(subdirectories are not well supported in g.extension of GRASS 6).
I re-installed v.strahler. Works fine but still no satisfactory result. I assume dependend packages are missing.
I assume that I have to reinstall v.mainchannel, r.strahler and r.broscoe as well? Did find v.mainchannel but not the raster packages, when I checked:
svn list https://svn.osgeo.org/grass/grass-addons/grass6/raster/
Or is there no need for independent install of the packages that were previously in the v.strahler folder?
Best regards
Ralf

thanks - my post was perhaps a bit confusing. I found v.mainchannel - but not r.broscoe and r.strahler (and I checked for them in raster - but realized they are as well in the vector folder).
However, I now managed to compile all addons v.strahler, v.mainchannel, r.broscoe and r.strahler and still get no reasonable results when processing a stream network (I attach a screenshot). I am using vector (stream network) and raster (DEM) maps for which I previously obtained good results - thus something must be wrong with the installation or something changed with the algorithm, as I can`t reproduce my old maps.
During installation of r.broscoe, r.strahler and v.mainchannel I get the following alerts:
/Users/ralfs/Library/GRASS/6.4/modbuild//dist.i386-apple-darwin10.7.0/scripts/v.mainchannel: line 72: exec: g.parser: not found
/bin/sh: g.parser: command not found
/bin/sh: …/…/locale/scriptstrings/v.mainchannel_to_translate.c: No such file or directory
But since the addons seem to work, this is may be not the problem.
I re-installed v.strahler. Works fine but still no satisfactory result. I assume dependend packages are missing.

Sorry, I was obviously too tired and didn't complete the demessification.
Now r.strahler and r.broscoe are in raster/ as they should have been since long:
