offtopic part here but:
If you mean Red Hat Enterprise Linux (AKA RHEL) 5.x then you can use
from RHEL 5.5 or CentOS 5.5:
rpmbuild --rebuild --with python gdb-7.0.1-23.el5.src.rpm
`--with python' would be default (but the binary rpms do not have it).
Such binary will not be unsupported.

You should compare what `file /var/tmp/core.5595' thinks about it together
with what prints just `gdb' when you run it:
This GDB was configured as "[...?]".
