According to Clyde Meli:
I had problems compiling an earlier beta under solaris 2.5.1 and left it at that when all the suggestions failed. I kept the release version (2.0) instead. But I might try again with this newer alpha at least on another machine.
I just checked: The problems you had with the last beta were related to a broken `parse.h' and perhaps `parse.c'. This should be corrected in the current alpha release. (If not, I am promising now to correct the source distribution.;-) IMHO it's a good time now to retry.
