[GRASS-user] problem installing perl mapscript for grass 6.2.1-3 on ubuntu Feisty Fawn

Hi everybody,
to run a perl script I need to install a per module: perl-mapscript. I’m on Ubuntu Feisty Fawn with grass 6.2.1-3.
When I use synaptic to install perl-mapscript, it said that I need to remove grass to install perl-mapscript.
If I remove grass and install perl-mapscript, and I want to reinstall grass, it said that I need to remove perl-mapscript. I can’t have the both in my pc
Is anybody know how to do to install perl-mapscript to use with grass
PS: I need perl-mapscript because I found a perl script which use the Douglas-Peucker algorithm for line simplification (this script use ESRI shapefile in input and output; I don’t know if the using of ESRI shapefile is the reason to need perl-mapscript module)
Thanks for your response
Mick

Mick,
I'm not familiar with synaptic but I think the main question is why do the packages conflict.?
Mapscript depends on mapserver which can depend on a whole host of things that could conflict with GRASS, ie. GD, freetype, ...
You could compile mapserver & mapscript from source and only include what input & output formats are needed.
If the code you found contains specific syntax which pertains to perlmapscript, ie. "new mapscript::shapeObj(-1);" then you need mapscript unless you rewrite the code to use something like GEO::Shapelib which has fewer dependencies but is only intended to access shapefiles.
