Re: installing a second gcc on the same machine

Something as "--badreloc" force someone to think that the rpm package
manager is evil
ad i don't think this (look at this
http://www.germane-software.com/~ser/Files/Essays/RPM_Hell.html<http://www.germane-software.com/%7Eser/Files/Essays/RPM_Hell.html>).
One thing marked as "--bad" is bad, not sure a normal mode of work. So it is
a matter of quality assurace : do to the right think so to have confidence
that the package preserve my system integrity ( and my time )

In the same vein, someone think that the package dependency are a nightname
and i don't think this: but they think are more simple disabling the
dependency, also when they  distributed only binary package - commercial
software or so. But it is this a nightmare : it is possible to upgrade the
system ? which truly requisite i have on this software ? Sure, it is
possibile to do : --ignorearch, --nodeps, ecc. But is it a sane thing to do
? But ok, i am a lazy sysadmin, i like pace of mind : so i like rpm.

I hope you agreed with most of the argument i have described.

Best Regards
