I'm game - I hit a similar problem on my old Sparc box last night (not rela=
ted=20
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 th=
e=20
linker to actually link against it, I do not know, especially since I didn'=
t=20
need to tell it -L/usr/lib to locate the .so... maybe if you're still stuck=
,=20
try telling it to link against absolutely everything.
