Python on Solaris: Wrong ELF class: ELFCLASS64

If “pip” installed 64-bit libraries, while python is a 32-bit binary, “pkg” might stop working with the following error messages:

ImportError: bootadm: fatal: /usr/lib/python2.7/site-packages/lxml/ wrong ELF class: ELFCLASS64
ImportError: python2.7: fatal: /usr/lib/python2.7/site-packages/ wrong ELF class: ELFCLASS64
$ file `which python`
/usr/bin/python:	ELF 32-bit LSB executable 80386 Version 1 [SSE], dynamically linked, not stripped

The workaround is to remove the corresponding python packages (in this case cffi and lxml), download and recompile them manually with “-m32”:

$ export CFLAGS="-m32"
