I don't understand this inconsistency between fortran and C linking on MacOS
X. 10.3. For the above fortran results you needed -lcc_dynamic, but
apparently not in this case.  Perhaps the -lcc_dynamic functionality is
supposed to be delivered by crt2.o and/or libmathCommon.A.dylib (which is
what libtool is convinced is necessary for fortran on MacOS X 10.3), but
those seem broken on your system. It appears you are stuck with the
workarounds you have discovered until at least crt2.o and
libmathCommon.A.dylib are straightened out.  I am wondering now whether your
g77 (which works closely with gcc) is consistent with your gcc package?

Hmm. that seems strange unless you are invoking the command from an
incorrect user account which doesn't have permissions to use that directory
or you have something left over from a previous install which you are now
trying to override from a different account.

I am surprised this worked at all from the build directory (what you are
calling the source directory here).  Instead, if you must use the build
directory rather than the install directory, use "make check". "make x01c"
should only be used for the installed versions of the examples or a copy of
them.
