my suggestion would be to attempt to upgrade to rh6.0, or build the python
rpm yourself by downloading the src rpm.. if you already have a production
system, the number of rpms you have to upgrade after you install libc6 is
quite large, and redhat has already done that work for you with the 6.0 cd.

in terms of breaking netcfg, unless you are using it heavily, that shouldn't
be all that big a deal. at least it didn't bring down my machine when I
upgraded. rumor has it that the 'lorax' (6.1) release of redhat has fixed
these issues, and I believe the patches are fairly simple to put into place
by hand-- there are issues with the change to the interpreter that enforces
the 'no keyword arguments after regular function arguments' feature.. i.e.:

'def foo(bing, baz=None, bar)' is no longer a valid expression and generates
a compile error, whereas in previous versions it compiled just fine (and
defaulted the argument to 'None').

in summary: upgrade to 6.0 (or 6.1 if you are brave-- it's still in beta)
or compile from a tarball and install it into /usr/local (doing the same
with the other extensions that you need).

hope that helps. ;)
