I guess all I had to do was install IlmBase 1.0.2. Shouldn't the
'configure' script check for this?

When building OpenEXR, it complained that memset was not defined, so I
had to add #include <cstring> to OpenEXR/ImathMatrix.

Then memcpy was not defined in exrenvmap/blurImage.cpp which could
again be fixed with: #include <cstring>

I am on Ubuntu 11.4 with g++ 4.5.2-8ubuntu4.

I hope these includes can be added so that the next person does not
run into the same problems.
