PKGSRC_COMPILER is the user variable which tells pkgsrc which compiler
you are using.  GCC_REQD is only valid if you have already set this to
'gcc'.  You'd normally set PKGSRC_COMPILER at bootstrap time using the
--compiler flag.

If a package specifically requires clang, then in the package Makefile
you can set PKGSRC_COMPILER+= clang, and then ONLY_FOR_COMPILER=clang.

Hope that helps,
