py-ephem fails with incorrect binary architecture

[amannucci (Anthony Mannucci)]

I installed py-ephem and received the failure listed below. I believe this is a problem with py-ephem itself. After installing pip using Macports, I followed the installation instructions on the Pyephem web site, which requires pip, and received the same error. I noted that the clang compiler was being used to build the code using pip. Prior builds for my other programs have used gcc. I am running OS X 10.7. I am running version 2.1.1 of Macports.

I resolved this problem by installing from source. I note that gcc was the chosen compiler during the source install (using python setup.py install).

Thank you!

Please update to MacPorts 2.2.1 by running "sudo port selfupdate".

Please remember to use WikiFormatting when writing in Trac.

The Cc field requires complete email addresses.

What does "port -v installed py27-ephem" say MacPorts thinks the architecture is?

What does "lipo -info /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ephem/_libastro.so" say the architecture of the file actually is?

What program are you running when this problem occurs, and what is its architecture, according to "lipo -info"?

What is /Users/mannucci/tle_progs?

What version of Xcode do you have installed?
