No, Guilllaume,
The query is regarding why, when this gentleman builds his own RPMs,
they all have a requirement on libsafe.so.2.0.
This is because when one uses libsafe in one's LD_PRELOAD (or
/etc/ld.so.preload) it makes ldd think that it's the binary that
requires the lib when in fact it is not. ldd is used in find-requires
to find all of the libs that a binary needs and enter those as
requirements in the RPM. The preload is fooling ldd and thus
find-requires.
There are two solutions, both of which have been brought up on the rpm
mailing list however the developers there seem to be too stubborn to
admit that this is a problem. The last time I brought this up they
insisted that it was the build machine that was incorrectly
configured (to use preloads - ~sigh~), not that it was a problem with
RPM's find-requires script.
One of the solutions is to use objdump instead of ldd. The other is
to exclude the results of $LD_PRELOAD and /etc/ld.so.preload from the
ldd output in find-requires with something like:

Incorporating the exclusion of contents from $LD_PRELOAD is left as an
excercise for the reader. :-)
