Solaris 7 Linking Question

I'm trying to build Postgres on Solaris 7 with the system's Kerberos
4 support. Once I got past the configure thinking it needed -ldes
when it really needed -lcrypt things went pretty well until . . .

Now I can look in /usr/lib/libkrb.{a,so} and see that routine is
defined. I can see that -lkrb comes after -lpq. I've tried it with
LD_LIBRARY_PATH undefined and defined to /usr/lib:/usr/local/lib.
Same result.

Must be something obvious, but I don't see it.
