Excuse me for not replying to your original email on pkgsrc-users as I
could have helped.

In mk/compiler.mk:
# COMPILER_USE_SYMLINKS
#       If set to yes, use symlinks for the compiler drivers, otherwise
#       shell scripts are created.  The default is yes.

However It's set to 'no' in mk/platform/Darwin.mk (see rev 1.38 of that file
for an explanation).

With all processing done in the mk/compiler/*.mk it is probably better
to use '${ECHO} ${CC_VERSION_STRING}' as -v doesn't work with all the
compilers supported by pkgsrc.
