I've tried, used rpm2tgz to convert the maya rpm's to .tgz files, installed them using installpkg.
everything went smoothly for that portion. had to install fam (file access monitering) and compile support into the kernel. set MAYA_LOCATION, AW_COMMON, NLSPATH and put /usr/aw/maya6.5/bin/ into the executable path. on my shell. (i think thats about all you'd ever have to do to get maya to work) all the other requisites where there..and i still couldnt get it to work, but nor could I find any more info to help me out.
but that's just my experience
