 Changes in commit [990215fb0308d43a17285250e7ea5832d78d341b/macports-
 ports] seem to prevent librsvg from building, the configure script fails
 at checking the C compiler. The compiler path is also passed as the first
 argument?
 The installation I'm working on is x86_64 emulated via Rosetta 2 on M1.

 {{{
 configure:4053: checking whether the C compiler works
 configure:4075: /usr/bin/clang /usr/bin/clang -pipe -Os
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -arch x86_64
 -I/opt/macports-x86_64/include
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -L/opt
 /macports-x86_64/lib -Wl,-headerpad_max_install_names -lobjc
 -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -arch
 x86_64 conftest.c  >&5
 ld: can't link with a main executable file '/usr/bin/clang' for
 architecture x86_64
 }}}
 Full log attached.

 After reverting to [f81d9284291514bc66032866fb3451a1e7689dbc/macports-
 ports] it builds without problems.
