Hi,
[debian/stable]
just updated to the latest 6.3-cvs. libproj didn't complile, complained
about missing -lgeos. this fixed it:
# ln -s /usr/liblibgeos.so.2.1.1 /usr/lib/libgeos.so
is this something new? The only thing that changed recently on my
machine was I moved libgdal temporarily out the way to test startup
errors.
or was it a recent change somewhere else?

That suggests that you need a -dev[el] package.
The unversioned symlinks are only needed when compiling, so they are
normally only included in development packages.

I'm fairly sure it's a GDAL thing. If GDAL was built with --with-geos,
-lgeos will probably appear in the output of "gdal-config --dep-libs".

Package `libgeos-dev' is not installed and no info is available.

$ dpkg -s libgdal1-1.3.1 | grep Version
Version: 1.3.1-0.dgis.stable.2
(this hasn't changed since March)
http://pkg-grass.alioth.debian.org/debian-gis/pool/g/gdal/
I am wondering what changed in the GRASS source so now we need geos devel
packages as well?
New GRASS 6.3+ packages will have to add libgeos-dev to the build-depends
list in the debian/control file.
?

Nothing changed in GRASS; it's GDAL that appears to have changed.
configure.in has:
GDAL_DEP_LIBS=`"$GDAL_CONFIG" --dep-libs`
...
GDAL_LIBS="$GDAL_LIBS $GDAL_DEP_LIBS"
So GRASS needs whatever gdal-config claims to need.
If GDAL is a shared library with dependency information, you don't
actually *need* those switches to link against GDAL, but we have no
way of knowing that gdal-config is lying.
OTOH, if GDAL is a static library, or a shared library which lacks
that information, we do need those switches or else unresolved-symbol
errors will occur.
New GRASS 6.3+ packages will have to add libgeos-dev to the build-depends
list in the debian/control file.
It only needs gdal-dev (or whatever it's called). The gdal-dev package
needs to list libgeos-dev as a dependency; if it doesn't, that's
gdal-dev's bug, not ours.
