This looks like a bug in the Redhat perl.  Under Mandrake 9, on this
same module, I get the following lines in the Makefile:

INSTALLPRIVLIB = $(PREFIX)/lib/perl5/5.8.0
INSTALLSITELIB = $(PREFIX)/lib/perl5/site_perl/5.8.0

Looking at the Mandrake 9 perl rpm yields this little tidbit:

Patch12:
perl-5.8.0-RC2-MakeMaker--have-PREFIX-appear-in-INSTALLs-variables-like-it-used-to-be.patch.bz2

So, it appears that Mandrake 9 patches MakeMaker to fix this
"new behavior".  I wonder why it was changed?
