libGLU @9.0.1_0+universal: undefined symbols

[JohannaXiao]

Hello, I tried to install molden, but it stuck at the libGLU. and the error message showing below:

Has duplicate #68334.

The log shows the problem is:

:info:build ld: warning: ignoring file '/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_x11_libGLU/libGLU/work/glu-9.0.1/.libs/libGLU.1.dylib-master.o': found architecture 'arm64', required architecture 'x86_64'
:info:build ld: Undefined symbols:

:info:build       <initial-undefines>
:info:build   _gluBeginPolygon, referenced from:
:info:build       <initial-undefines>

So: you're trying to build universal on an arm64 Mac, but it has only built libGLU.1.dylib-master.o for arm64, not universally.

This looks like the same libtool bug we observed elsewhere when using Xcode 15, which was fixed in the libtool port in [85058b4d9bc2b7ab451f7ce622a2786078462ee1/macports-ports] and which now needs to be propagated manually to the zillions of ports like libGLU that include a bundled libtool.

We can probably just use the second hunk of that patch in ports, which will always disable the workaround for lack of -single_module support, which is fine because we only support 10.4 and later. The patch in libtool is more thorough for the purpose of being upstreamable.
