The alpha issue should be easy to fix: it is just a code path which
has never been tested so far, but the code is there.

The ppc one is more annoying, and known. The problem is that linux on
ppc uses the IBM format for long double (sum of two double), which
requires to implement non trivial, heavily platform dependent code. I
have just added code to correctly detect the long double format at the
configure stage.

Do you have shell access to the machines ? It would makes the work
much easier for me to fix those issues,
