For png, the symbol missing is not one the configure test is looking for,
so it seems your png library is incomplete.  I'd rebuild it.  It's also
strange since on Solaris it would be normal to have a shared library.

For jpeg, I think you are seeing a consequence of the incomplete libpng.a,
which you can't link *anything* against.  To stress this: it is not that
it is missing things R needs but that it is missing things it needs
