Comment (by ryandesign):

 Again, it's simpler if you just attach the original text output rather
 than converting it to something like a pdf. A text file can be viewed
 directly on the web whereas a pdf or doc file needs to be downloaded and
 opened into a separate application.

 The terminal transcript in your pdf shows that m4 failed to configure.
 Therefore, please attach the main.log and config.log from that failed
 attempt so that we can see what went wrong. The paths to those files are
 shown in your transcript.

 Your transcript also shows that MacPorts is installing xfig's dependencies
 universal (for both x86_64 and arm64). Normally ports are not installed
 universal, but MacPorts will install dependencies universal if it
 determines that it is necessary to do so. For example, if a port to be
 installed does not support arm64, then it will be installed for x86_64,
 and to do that its dependencies need to be installed universal.
 Unfortunately MacPorts does not print any output identifying which port is
 causing this to occur. Since building universal is not the norm, it could
 be the reason for the configure failure, but we won't know until we see
 the logs.
