If I were at my other residence on DSL high speed I would download the package and have a look at the makefile where I'm guessing the offending command originates. It looks similar to a command to compile 32bit on a 64bit OS, only with extra options or parameters or something, 'pcs' or something.....
Anyway, I'm on dial up, can't offer much more at this point.
