currently your source package demands the user to
$ make -f Makefile.dist
while the common way of handling configure script
generation is an ./autogen.sh or (better) ./bootstrap.sh script.
Basically, you could keep everything in place as it is,
and add a ./bootstrap.sh script to the distributed tarball with the contents:
make -f Makefile.dist
I am suggesting this because by using conventional methods, your source package is automatically installable using existing OS-independent tools like the gnu source installer I am maintaining.
Thanks for considering this feature enhancement,
