[GRASS5] GRASS 5.1: MacOSX compilation?

[Markus Neteler]

Currently I try to compile GRASS 5.1 on Mac OSX.

Thanks to the recent update of 'aclocal.m4' by Paul the
'configure' runs well now, using following parameters:
http://grass.itc.it/grass51/source/conf_scripts/macosx/
-> conf51_macOSX.sh

All libraries compile as well, but there is a problem
compiling modules (as well as some 'test' programs within
the libraries and the 'form' program). The compiler line
for linking modules seems to be wrong:

Example:

[timonchiotwin:~/grass51exp/raster/r.average] markus% make
gcc -I/Users/markus/grass51exp/include -I/Users/markus/grass51exp/dist.powerpc-apple-darwin6.6/include -I/usr/X11R6/include -I/sw/include -g -O2  -Wall -Wconversion -Wno-implicit-int  -I/usr/X11R6/include -I/sw/include    -I/Users/markus/grass51exp/include -I/Users/markus/grass51exp/dist.powerpc-apple-darwin6.6/include \
        -o OBJ.powerpc-apple-darwin6.6/main.o -c main.c
main.c: In function `main':

make: *** [/Users/markus/grass51exp/dist.powerpc-apple-darwin6.6/etc/bin/cmd/r.average] Error 1

Knowing almost nothing about Mac OSX I would like to ask here for help.
Some 'gcc' flags seem to be missing.

Thanks
