I would have said "ldd postgres" would work on any ELF system and show you all
the library so versions it depends on. I guess that only helps if it actually
builds and then fails the regression tests -- not if the build fails.

On Debian it would be useful to do something like below. Though note that a)
this depends on having a postgres package installed which the build machines
may not have and b) it shows the libraries that package depends on not the
versions of the *-dev packages installed.
