Problem is, this assumption is often true. The LSB is supposed to help 
with the file location part, but functionnality-wise, the glibc-2.3.1 
shipped with RH8 doesn't use NPTL, while the version (IIRC) shipped in 
Debian unstable did a few months ago. So if your package (RPM, deb, tgz, 
anything via alien) is compiled to use it, it can be unusable on some of 
the other distros, even when installed packages versions are the same 
(because of different configuration choices by distros).

What would be better is to have them moved to Sourceforge, alongside the 
other ones. Some small things would need to be improved though 
(documentation is not built, for example).
I should have a working RH9 setup early next week (if time permit), so I 
may tackle it.
