Even if you managed to install both versions at the same time (not
only the library but also the devel-package), it would not work. When
checking the dependencies rpm will probably use objdump or ldd[1] on
the resulting binary which will find the system Glibc (2.3) and add it
as dependency to the rpm. The chroot-idea will work.

BTW, what is so bad about compiling bogofilter?

cat ~/.rpmmacros
%_topdir                /tmp/ametzler-redhat-build

mkdir -p /tmp/ametzler-redhat-build/{SPECS,SOURCES,BUILD,RPMS/i386}
rpm -i bogofilter.src.rpm
cd /tmp/ametzler-redhat-build/SPECS
rpm -bb bogofilter.spec

[1] I do not know, but that is how works on debian.
