It's LGPL so it's compatible (only the readline part is subject to GPL,

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

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
bepublished on any terms. We encourage authors to publish on Free terms.
