Re: pyilmbase problems importing imath

I see, thanks for the qualification. I have built with gcc4.4.6 all the way
up to 4.7.x so not sure that is the issue.  I think boost 1.5.1 is good for
the later releases, certainly 2.x, but again, we built 1.x versions with
1.39 for quite a few years without any issues.

I'm not sure why you would be seeing this linux as is...
