First problem occurs when building Scope::Upper (which is a TryCatch prerequisite): 
Upper.xs:1331:11: error: ‘CXt_LOOP_FOR’ undeclared (first use in this 
+function)
      case CXt_LOOP_FOR:

Therefore Scope::Upper fails to build and does not get installed.
Versions of perl prior to 5.24.0 define CXt_LOOP_FOR in cop.h, but not perl-5.24.0.
But it's worse than that - see the bug report.
That thread contains a patch which might solve your issue if you wish to apply it.

TryCatch therefore fails its tests because Scope::Upper cannot be found.
Therefore, TryCatch fails to install. You could force the installation but that won't help because TryCatch.pm needs to load Scope/Upper.pm and there's no way of installing a loadable Scope::Upper when it fails to build.

I would take this up with the authors of these 2 modules.
Does TryCatch *really* need to use Scope::Upper ?
Maybe the Scope::Upper author would agree to upload a devel version of Scope::Upper that at least builds (despite his reservations about the mileage that would provide). It could be that the broken aspects of Scope::Upper don't impact on TryCatch.pm and it's just a matter of installing the patched version.

Or you could consider using something else .... or revert to perl-5.22.x or earlier.

Cheers,
Rob
