I'm game - I hit a similar problem on my old Sparc box last night (not related
to libpq specifically). I did this:

$ uname -a
SunOS sparc4 5.6 Generic_105181-05 sun4m sparc SUNW,SPARCstation-4
$ gcc -lpthread test.c # this is Bruce's thread test app
Undefined first referenced
symbol in file
gethostbyname /var/tmp/cc31rpyq.o
ld: fatal: Symbol referencing errors. No output written to a.out
collect2: ld returned 1 exit status
$ gcc -lpthread -lnsl test.c # this works

libnsl contains the gethostbyname function... why on earth I had to tell the
linker to actually link against it, I do not know, especially since I didn't
need to tell it -L/usr/lib to locate the .so... maybe if you're still stuck,
try telling it to link against absolutely everything.
