So, for those with the ps.map problem with d.m in grass 5.7, it is possible to
fix by installing fftw2.15, which will provide libfftw.so.2, and will be
necessary to make a link to it named lidfftw.so.2, in /usr/lib.
the package can be found in rpm format (I guess that mandrake uses it) and in
tgz (for slack users).
if anyone needs the tgz package, I can send it.
