Thanks to David Billinghurst for finding his email. I have now contacted
Michael J.D. Powell, the author of COBYLA, and he says:
I wrote the Fortran package COBYLA ....
I hope that my contributions are
helpful to you. I believe in making software available freely, so
there are no restrictions on the use or distribution of COBYLA.
I hope this reply answers your question.
So, I'll add colbya in share/colbya shortly.
