Problem while building with copr (failing for no apparent reason)

[José Matos]

Hi,
	I am using copr to build another candidate for lyx-2.1 and the build fails for me with no message related with the failure:

http://copr.fedoraproject.org/coprs/jamatos/lyx-21/builds/

The only file I get is in this case build-9287.log that is useless.

I have built the package locally on mock I have no problems building it.

Regards,
