adding builtin support

[Jörn Clausen <joern.clausen%uni-bielefeld.de@localhost>]

Hi!

I am struggling again to add builtin support for Solaris to a package. 
This time I'd like to use native openssl (actually the on in /usr/sfw) 
instead of security/openssl. I have severe performance problems in a 
productive radius server.

So far I have done this:

--- builtin.mk  2011/05/24 08:14:39     1.1

and added "PREFER_NATIVE = openssl" to mk.conf. Now I get:

$ bmake show-var VARNAME=USE_BUILTIN.openssl
yes
$ bmake show-var VARNAME=BUILTIN_PKG.openssl
openssl-0.9.7d
$ bmake show-var VARNAME=CHECK_BUILTIN.openssl
no
$ bmake show-var VARNAME=BUILDLINK_PREFIX.openssl
/usr

Maybe someone can give me a hint on what to check/fix next. What is 
missing to set BUILDLINK_PREFIX.openssl correctly? What variables are 
actually checked when a depending package decides to take the native or 
the pkgsrc version?
