Hello all,

Thanks for you help all of you. All your advises were very helpful to 
me and I think I've a better understanding of the compilation process 
and its caveats and traps...

The DOCSTRINGS error is mainly due to the options passed to the 
compiler. I use a 10.3.7 OS X, XCode 1.5 (with november 2004 update) 
and gcc 3.3.x build 1671.

Well the default gcc options given by the configure script build 2.1.64 
without errors... but poor perfs. The better I can have (for the 
moment) is to pass

FFLAGS='-O5 -funroll-loops'
CFLAGS='-O3 -mcpu=G5 -mtune=G5 -faltivec'


I'm going on finding the best options... and tell you back

Thanks again

SAmir Sharshar
