Comment (by mbaehr):

 I've been digging on this issue quite a bit today, and as far as the
 packages that fail with an include error from libstdc++ (see #70749,
 #70716), the problem is specific to the environment when MacPorts is
 executing either the configure or the build step. By process of
 elimination from my own testing, this particular variable seems to be the
 root of the issue:

 DEVELOPER_DIR='/Library/Developer/CommandLineTools'

 If I reproduce the precise environment that MacPorts is exporting, minus
 that variable, and execute the same command, the failure does not occur.
 If I export that variable, it does. Could be a red herring but I'm having
 a lot of success with multiple packages so far.
