New description:

 Hi rasmol fails to build on M1/bigsur with the following error:

 {{{
 MOLDIR=\"/opt/local/share/rasmol/\" -DTHIRTYTWOBIT
 -D_USE_RASMOL_H_     -c -o repres.o repres.c
 :info:build clang: clang: clang: clangclang: : error: no such file or
 directory: 'DarwinMachineDefines'
 }}}

 It seems like an old definition that was recently removed in macOS, but I
 can't find any reference to it in the source code and google is unhelpful.
 Removing the definition "DarwinMachineDefines" in the makefile seems to
 fix it (it installs OK after that and runs fine) but not sure the best way
 to patch the port (bit of a port newbie) and whether removing this is in
 general safe.

 Any thoughts?

 Many thanks,

 Richard

Comment:

 Normally you should submit a main.log file when you encounter a build
 failure. But I tried a build on our Apple Silicon build machine and got
 the same problem, so that log is sufficient:

 https://build.macports.org/builders/ports-
 11_arm64-builder/builds/20536/steps/install-port/logs/stdio

 Something is supposed to be defining `DarwinMachineDefines` to the set of
 flags that are appropriate for your system. That "something" was probably
 written before Apple Silicon machines existed, so it doesn't define
 `DarwinMachineDefines` to anything on your system, so the literal string
 `DarwinMachineDefines` gets inserted instead, which is wrong.

 I haven't yet found what is (supposed to be) defining
 `DarwinMachineDefines` in this case. I did find it for example here:

 https://cgit.freedesktop.org/xorg/util/cf/tree/darwin.cf

 And I found a previous reference to this kind of problem in #22528 (which
 was on Snow Leopard which was when Apple's gcc started defaulting to
 64-bit compiles, so at that time it was probably the x86_64 architecture
 that wasn't being handled in the code.)
