Then this is the way to go.

Do you /think/ so or have you /tried/ an experienced this problem?

Actually, you do want to use /usr/bin/orbit-idl-2 at cross-build-time: it
is "used" (=executed) to process idl-files shipped with ORBit2 to create
more c-files to be cross-compiled.

This does /not/ mean /usr/bin/orbit-idl-2 will be "used" (=copied) to the
target machine instead of another cross-compiled orbit-idl-2 binary.
