Build and install - how to avoid dependency on specific library version

Folks,
I ran the build on a different Solaris machine and installation
immediately failed with this message:

ld.so.1: postgres: fatal: libresolv.so.2: version `SUNW_2.2.2' not found
(required by file  .../<some-path>/postgres)


Looking at the build machine:
/usr/lib>  /usr/ccs/bin/elfdump -v libresolv.so.2

Version Needed Section:  .SUNW_version
            file                        version

                                        SUNWprivate_1.1
            libnsl.so.1                 SUNW_1.9.1
                                        SUNWprivate_1.4
            libc.so.1                   SUNW_1.22
                                        SUNWprivate_1.1

Same check on the installation host:

%  /usr/ccs/bin/elfdump -v libresolv.so.2

            libnsl.so.1                 SUNW_1.7
                                        SUNWprivate_1.4
            libc.so.1                   SUNW_1.22

       [6]  SUNWprivate_2.1

So it appears the problem is that when I build Postgres SUNW_2.2.2  is
available, and somehow
it gets registered with the binary  (maybe though configure ?)
On the target machine the highest version of libresolv  is SUNW_2.2.1,
so initdb fails.

I've got this far, but I don't know how to deal with this problem.
Ideally I'd like to continue running builds on this new machine, but I
cannot assume that every installation host
will have this particular version of libresolv.

Is there a reasonably good way of handling this situation?

If it matters this is Postgresql 7.3.10     (Yeah, I know, don't ask me
why...)

Thank you,
Michael.
