I've just added a package "url2pkg" (it's in the pkgtools category), which
is intended to help creating packages. Just give it the URL of a source
archive, and it will make some effort to create a binary from it:

 - setup a basic Makefile
 - run "make fetch" and "make makesum"
 - generate a dummy pkg/PLIST
 - run "make extract"
 - try to find out the WRKSRC (if needed)
 - try to find out of this package uses GNU auto-configure

After that, you're left on your own, but I think it's better than nothing. 
At least the reactions I got when showing it to some people indicated
this. YMMV. 

Let me know if you have some comments or want to donate a man-page. :)
