compile enable socket

[Anon]

Been running PHP4 as a cgi module on SunOS and want to enable sockets,
But am having a problem recompiling it with "enable socket".

--with-mysql=/usr/local/mysql'
--with-gd'
--with-zlib'
--with-png'
--with-xml'
--enable-ftp'
--enable-discard-path'
--enable-sockets'

It produces the following error:
"Seg fault"

Anyone have any ideas ?
