Besides mixing GLSL versions like Ian said, there's other issues with shader \
concatenation such as #pragmas and preprocessing.

Nevertheless, concatentation will probably work fine in most cases and it's \
relatively simple to implement.  I've been working on it a little bit in the evenings \
and should have it done by the end of the week.

A proper solution to this will probably have to wait until we have a new compiler...
