It's LGPL so it's compatible (only the readline part is subject to GPL,
we're familiar enough with that though).

http://www.gnu.org/software/guile/docs/docs-2.0/guile-ref/Guile-License.html

The Guile library (libguile) and supporting files are published under
the terms of the GNU Lesser General Public License version 3 or later.
See the files COPYING.LESSER and COPYING.

C code linking to the Guile library is subject to terms of that
library. Basically such code may be published on any terms, provided
users can re-link against a new or modified version of Guile.

Scheme level code written to be run by Guile (but not derived from
Guile itself) is not restricted in any way, and may be published on
any terms. We encourage authors to publish on Free terms.
