In the future, please use WikiFormatting and add the port maintainer(s) to Cc (port info --maintainers serf1), if any.

It looks like there's something odd with your setup:

File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/struct.py", line 1, in <module> :info:build from _struct import * :info:build ImportError: No module named _struct

This should work

Out of curiosity, why are you trying to build for 32-bit, rather than 64-bit as would be usual on High Sierra (and indeed on Lion and later)? Have you deliberately (or accidentally?) changed build_arch in macports.conf?

[maurogaio]

python27: I've fixed the problem with my python setup, but it still does not work.

32-bit : Yes initially I wanted to try to make a migration to retain the ability to run afterwards old applications.

Solution: I removed the 32-bit option and reinstalled macports completely, it works

[ryandesign (Ryan Carsten Schmidt)]

I am able to reproduce this issue, if python27 has been installed for arch i386 only on a 64-bit computer. I don't think we've encountered anyone else trying to use such a configuration, so I don't think we're likely to spend a lot of time trying to fix it. On a 64-bit computer, set build_arch in macports.conf to x86_64 (that's the default) and let MacPorts build 64-bit software. If you still want 32-bit support, make sure universal_archs is x86_64 i386 (that's the default) and install ports with the +universal variant, which will give you programs and libraries that can be used from both 32-bit and 64-bit. I have most of my ports installed universal on High Sierra and it works fine for serf1. Trying to build serf1 with the 32-bit part of the universal python27 (by editing the serf1 portfile and changing build.cmd to arch -i386 ${prefix}/bin/python2.7 ${prefix}/bin/scons) still fails (with a slightly different error: ImportError: dynamic module does not define init function (init_struct)), so there may be a general problem with 32-bit python27 on 64-bit Macs, or it may be a problem specific to scons.
