I had to apply the following patch to libpcap to be able to get a
working shared libpcap library on Solaris (don't remember the version of
Solaris this was for, though):

It's been a while since I used this but I remember that it worked back
then. It's kind of hackish (the real solution would be to move to
libtool, as Guy says) and no promises that it'll work but should give
you a starting point to play with.
