It is still maintained, but they don't release often and the shell scripts per platform are currently not maintained anywhere central (FreeBSD and Debian have them in their respective package systems), so I have nowhere to submit it to.  (/cc @rdicosmo and @vstakhov in case they know better)

Either way, the patches for 1.8.0 will never be upstream -- the shell script involved will be rewritten to be portable from the start, which @vstakhov had in a Gist somewhere.  This port does give us a working version of the Aspcud toolchain on MacOS X, which is very useful in the short term until the upstream improvements can happen.
