You realize of course that 9.0.x has been out of support for years now;
whether there is a bug in it or not, we won't be fixing it.
Having said that, current versions of PG build fine on RHEL6 with
--with-gssapi, and all the dependent libraries get linked AFAICS.
I don't know of any reason why that would not have also been true
of 9.0.x. The configure fragments you presented do not constitute
evidence of any actual problem.
You might try --with-gssapi instead of --with-krb5; the latter
switch had already been deprecated for some time as of 9.0,
I think.
