mono build error

[Dries Michiels]

When building mono from source with Synth I get the following build error:

Try to set MAKE_JOBS_UNSAFE=yes and rebuild before reporting the failure to

the maintainer.

Stop.

make: stopped in /xports/lang/mono

 

 

Any idea's? I have DEFAULT_VERSIONS += python=3.6 in make.conf, as I see
from the log, the build process can't seem to locate python2.7.

Is this the root cause? I'm just speculating. If this is the case, should we
define a hard dependency for mono on py2.7, if it can't deal with py3.6?

 

Thanks,

Dries
