pkgsrc and native gcc on Solaris

[Raymond Meyer <raymond.meyer%rambler.ru@localhost>]

Hi, I've got a native installation of gcc on Sparc Solaris under /opt/gcc. Sun
call it gcc for Sparc systems, which uses optimising Sun code generator for
sparc platform, see:

Will pkgsrc be able to figure out by itself that it needs to append
-Wl,-R/opt/gcc/lib when building packages, or do I have to set it manually?

Thanks.
