The CVS version (HEAD branch) now has a perl based template "system" in place to generate more standard makefiles that can be used with any type of make(1). So far, it looks very promising and takes away many build problems for lots of users that aren't running some form of BSD :). Also, a very simplistic build.sh is supplied.
I have to refine the perl script that generates the makefile somewhat more (put in more error checking etc.), but it's useable.
