The guile package in rawhide is planned for update to a new major release. In a test rebuild of all packages depending on guile, mdk has failed to build. Rebuild results: http://mlichvar.fedorapeople.org/tmp/guile/rebuild/ New guile packages: http://mlichvar.fedorapeople.org/tmp/guile/ Please close this bug if a new upstream version of mdk which works with the new guile is available or if you think the current version can be easily fixed. It doesn't have to be commited in fedora git, we are just trying to find out if we need to delay the guile update (or make a guile-compat package).
MDK v 1.2.7 should work with Guile 2.0 now, according to this comment http://lists.gnu.org/archive/html/guile-user/2013-02/msg00169.html
I updated mdk to version1.2.7 in rawhide (f19).
This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle. Changing version to '19'. (As we did not run this process for some time, it could affect also pre-Fedora 19 development cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)
