Since "Requires squid" is gone, we cannot be sure the squid group exists.
revert group ownership in %files to root
"%make" and "%makeinstall_std" macros does not exists in RHEL5, revert to
"make" and "make DESTDIR=%{buildroot} install" which are more compatible
- remove %mkrel macro (mdv specific)
- add BuildRoot macro for compatibility with RHEL
- remove perl special files (perllocal.pod and packlist) not packaged
