M2Crypto dependency not declared.
M2Crypto is required by the glue library. This could be solved by patching upstream packages that use this functionality as we've also reported here.
https://github.com/ligovirgo/dqsegdb/issues/49
However, since the code is from glue, it should probably be listed as a dependency of this package. Note this is a blocking problem for the next pycbc release.
