Can't replicate, could you confirm on the latest version of nim?

Only some versions of cligen exhibit the issue, at least one of which is v 1.3.2:

     Error: Aborting installation due to build failure

cligen@1.3.2 satisfies inim's (0.6.1) constraint of `cligen>=1.2.0, therefore users who already have these "broken" cligen versions on their system would result in a failed build for inim.

#131 should resolve this issue, we just need to issue a new release (tag) of inim.
