Could you please check for compiler warnings or errors during the
build.  In particular, look to see if any variant of the
gamma function is mentioned in connection with a message on the
order of "implicit declaration of built-in function =E2=80=98lgamma=E2=80=
=99".
But please report all warnings or errors.

Also please look in the file config.h created while preparing
the cvs distribution and tell us whether HAVE_LGAMMA is defined or
commented out.
