Hi David,

if you look at the build log, the error is:

pycaml_ml.c:1151: error: 'PyImport_ImportModuleEx' undeclared here (not
in a function)


If you dig around a bit, you find that in Python 2.6, this is strictly a
#define, which is incompatible with pycaml_ml.c's use of it - whereas in
Python 2.5, it was also provided as a real entry point for compatibility.

Rather annoyingly, if you dig into Python's svn repository, it looks
like this compatibility provision may have been *accidentally* reverted
- http://svn.python.org/view?view=rev&revision=59678, look at the
changes to import.c and import.h.

Accidentally or not, it looks like pycaml will need to be adapted to not
use that function.

Max.
