Help with Install on Solaris 10 (UltraSparc 3)

When I install wxWidgets everything seemed to go fine. Then when I compile PGAdmin3 1.2.2 I get:

Undefined first referenced
symbol in file
gethostbyname pgConn.o (symbol belongs to implicit dependency /usr/lib/libnsl.so.1)
inet_addr pgConn.o (symbol belongs to implicit dependency /usr/lib/libnsl.so.1)
inet_ntoa pgConn.o (symbol belongs to implicit dependency /usr/lib/libnsl.so.1)
ld: fatal: Symbol referencing errors. No output written to pgadmin3
collect2: ld returned 1 exit status
make[2]: *** [pgadmin3] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Anyone had experience with this error? I can't believe that gethostbyname is unresolvable.

I see that my libs are there and I have even updated my windex:
man -k gethostbyname:
endhostent gethostbyname (3nsl) - get network host entry
gethostbyaddr gethostbyname (3nsl) - get network host entry
gethostbyaddr_r gethostbyname (3nsl) - get network host entry
gethostbyname endhostent (3xnet) - network host database functions
gethostbyname gethostbyname (3nsl) - get network host entry
gethostbyname_r gethostbyname (3nsl) - get network host entry
gethostent gethostbyname (3nsl) - get network host entry
gethostent_r gethostbyname (3nsl) - get network host entry
sethostent gethostbyname (3nsl) - get network host entry

I did make the mistake of trying to compile once before having installed STC and OGL, but I corrected that. While making that mistake, I arbitrarily copied over the entire headers folder from wxWidgets into /usr/local/wx-<ver>/wx/include. Unfortunately, now I don't know what to delete but that shouldn't cause this problem should it?
