Yes, but you must tell pkg-config which libraries to use. pkg-config
is for setting flags, not finding the libs.

AFAIK this option is not available.

It is just for development. Using pkg-config this way allows specific
binding to either the OpenCSW X11 libs or Sun X11 libs with gtk+ on
compilation. This separation was intended when we introduced /opt/csw/ 
X11.
Is this case, however, it is not useful. As it is only relevant in
compilation and integration is well understood and easy in both manual
and GAR builds it shouldn't do too much harm, though.
