I am trying to upgrade Amanda site wide to 2.6.1, and I just ran into what
may be a big deal. 2.6.1 apparently needs glib, now I did not think this was
going to be too much of a problem. Just another download compile cycle
thing. But on the first system I tried to build it from source on I ran
into a bit of a problem, which led me to actually read the install
instructions, imagine that :-)

Now I am worried as it unpacked, I noted a number of files in a directory
that seemed to pertain to specific machine types. Now I see that the list of
supported hardware/OS combinations is very limited. I need to make this
work on HP-UX 10.20 on PA-RISC, and Solaris 5, and 8 on SPARC. It does not
appear that these hardware/software combinations are supported for glibc.

I don't understand what glibc is, clearly. I thought that it was the libc
that is used on Linux distributions, but that must not be the case. What
does it bring to the party that Amanda needs? 

And while I am asking, what does pkg-config bring to the part that
configure does not?
