Howdy All I just installed FC8 this last week and was getting ready to to update some PHP-PEAR modules when I ran into some error messages about not being able to find some shared object files. As I do not know anything about packaging rpms thought I would let the list know and maybe someone could do what needs to be done so that others may be able to save a little time. According to what I got the following packages are required by PHP-PEAR compat-expat1.i386 0:1.95.8-3 / libexpat.so.0 fftw2.i386 0:2.1.5-15.fc8 / libfftw.so.2 the fftw3 package was already on my system and not sure if installing the fftw2 package might have messed anything up but yum did not complain about it so hope it is ok. lapack.i386 0:3.1.1-2.fc8 / liblapack.so.3 Hope this might help someone Don
