Sigh.  It -should- have given you a nice message, but apparently that
was one of the bits that needed a 1.1 specific workaround.  What fun.

I will fix the error reporting.  Good catch.

With that fixed, you get messages like:
    *** failed to import extension cdm from /builds/work/illumos/il-cdm-16/usr/src/tools/onbld/hgext/cdm.py: Version Mismatch:
    Scm expects Mercurial version 1.3.1, 1.4.2, 1.5.4, 1.6.2 or 1.6.3, actual version is 1.5.1.
