Yes, indeed. The autotools build is broken on 64 bits Macs because, contrary to the assumption of the autoconf script, the compiling toolchain supports three architectures there and not just two. You can workaround this problem by disabling the perl interface if you don't need it (--disable-perlint parameter of the configure script) or by using the classical build. There are also two other problems with the autotools stuff. The first one is the missing libtoolize binary called from the bootstrap.sh script (on Mac it's called glibtoolize). Also, the autotools build tries to link the xrootd binary to a dynamically loadable module which results with a linking error. On Mac there is a clear distinction between loadable modules and shared libraries which is not the case for the ELF systems where both are the same and this is why this problems has been introduced and not spotted earlier. Anyways, thanks for reporting. I will be fixing that on Monday.
