Thank you, I remember seeing this now.

The problem I was having related to different builds overwritting
each other's .o files.  It seemed as if the compile code was
generating intermediate .o files with names I could not control, and
they were clashing.

Whether that was true or not, I've since moved the egg to use the
make command, and using the advice from issue #9 I got my egg
compiling with both a library and an executable.

Thank you!
