I'd suspect a local python-cffi more than a local jack. The jack module doesn't involve any built bits.

For reference, see https://github.com/ovenwerks/studio-controls/issues/43 * Per the bug report, the following error is being thrown: SystemError: ffi_prep_closure(): bad user_data (it seems that the version of the libffi library seen at runtime is different from the 'ffi.h' file seen at compile-time) * Based on this error, and based on the build time of python-cffi and libffi in relation to cffi, it appears as though python-cffi and libffi were built on an older version of cffi. This explains the error. [Test Case] * A certain number of users have reported that simply running studio- controls causes this error. [Where problems could occur] * Since this is a no-change rebuild being requested, the possibility of breakage is slim to none. We are introducing no new changes here, but rather, resolving a regression that happened as a result of a newer version of cffi being introduced without a rebuild of dependencies. * If any problems happen, it would be a result of applications using python-cffi and expecting this bug with built-in workarounds. I can't imagine such a case exists, so this is just a stretch.
