You can convert the Debian package into a generic
.tar.gz
by using
alien.
I considered putting a tarball on the web site, but the
pppd
binary has been linked against the
libcrypt
shared library which I would also need to distribute, and I'm uncertain about possible (albeit ridiculous) U.S. export restrictions on this library.
As far as I know, as long as you have the necessary shared libraries, only the
pppd
binary is needed to run PPP using the PPP kernel - a Debian environment should not be required.
