Hi,

as net/userppp is quite old, I try to update the package to
a more recent version. As the userppp sources are extracted
directly from the FreeBSD source, there are some
    .include <bsd.prog.mk>
(and similar) statements in Makefiles.

How should I handle these in order to avoid installing the
programs/libraries in /usr/bin, /usr/lib, etc? Are there any
pendants for pkgsrc which I can use directly? Or are there
any .mk files which I can .include before bsd.prog.mk?
(Setting LIBDIR directly in the Makefile would probably work,
but that seems to be an ugly hack.)

Kind regards
    Ingolf
