samba4 PLIST issue on different platforms

[Mark Davies <mark%ecs.vuw.ac.nz@localhost>]

samba4 fails to install on linux (possibly other platforms) because the 
files produced are slightly different from what the PLIST expects.  This 
is because of differences for different platforms in nsswitch/wscript_build.

netbsd builds libnss_winbind.so
linux builds libnss_winbind.so.2 and libnss_wins.so.2
freebsd builds libnss_winbind.so.1 and libnss_wins.so.1
sunos would have built libnss_winbind.so.1 but pkgsrc patches it to 
build libnss_winbind.so

Should we similarly patch the linux and freebsd entries or fix it some 
other way?

cheers
