It seems there's a problem with python, because the logfile says

:info:build /bin/sh: /opt/local/bin/xml2po: /opt/local/bin/python2.7: bad interpreter: No such file or directory

Cleaning and re-running configure should pick up a version of python that works. If it doesn't a dependency on python27 should probably be added to the evince port.

Please use WikiFormatting and remember to cc/assign to the maintainer, if any.

Your logfile shows your build of evince was not a clean attempt:

35	:debug:main Skipping completed org.macports.archivefetch (evince)
36	:debug:main Skipping completed org.macports.fetch (evince)
37	:debug:main Skipping completed org.macports.checksum (evince)
38	:debug:main Skipping completed org.macports.extract (evince)
39	:debug:main Skipping completed org.macports.patch (evince)
40	:debug:main Skipping completed org.macports.configure (evince)

Please run

sudo port clean evince

and try again. Attach the new main.log, if it fails again.
