OK, if this the first step, then I'm confused.
/usr/bin has this:

-rwxr-xr-x 1 root root 14512 Jan 14  2010 gcc
lrwxrwxrwx 1 root root    62 Nov  6 14:08 gcc-4.4.4 ->
/usr/x86_64-pc-linux-gnu/gcc-bin/4.4.4/x86_64-pc-linux-gnu-gcc
-rwxr-xr-x 1 root root 21709 Sep 22  2009 gcc-config
-rwxr-xr-x 1 root root 14512 Jan 14  2010 x86_64-pc-linux-gnu-gcc
lrwxrwxrwx 1 root root    62 Nov  6 14:08 x86_64-pc-linux-gnu-gcc-4.4.4 ->
/usr/x86_64-pc-linux-gnu/gcc-bin/4.4.4/x86_64-pc-linux-gnu-gcc


So can I just rebuild the links, as  it is fine
in /usr/bin:

file gcc
gcc: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked
(uses shared libs), for GNU/Linux 2.6.9, stripped


Or do I use quickpkg to fix it, since the binary is 
in place?  (confused here so detail is appreciated!)

I already downloaded gcc-4.4.4 but it will
not build, so the symbolic link being used
is broken?
gcc-config -l
 * gcc-config: Active gcc profile is invalid!
 [1] x86_64-pc-linux-gnu-4.4.4


I understand that quickpkg can be used
to protect gcc in the future, but, I think
I need to use the /usr/bin binary to rebuild 
the links and then the entire (gcc) package
from sources?


confused,
James
