However TryCatch is installed but in a path that is not in @INC, TryCatch is in ~/.cpan/build/TryCatch-1.003002-0KBiDH/lib!

As others have stated, it is not installed there - that is where it was built.
And, if any of the tests failed, then it won't be installed at all unless you use force:
cpan -fi TryCatch


Adding ~/.cpan/build/TryCatch-1.003002-0KBiDH/lib to @INC will probably not work.
It will enable TryCatch.pm to be found, but then the TryCatch loadable object (.so or .dll, depending upon platform) will not be found. For the loadable object to be found you probably need to also add ~/.cpan/build/TryCatch-1.003002-0KBiDH/blib/arch to @INC.
This assumes that ~/.cpan/build/TryCatch-1.003002-0KBiDH/blib/arch/auto/TryCatch/TryCatch.so (or .dll) exists, and this is not necessarily the case.
The existence of ~/.cpan/build/TryCatch-1.003002-0KBiDH/ indicates that an attempt to build and install TryCatch was made, but it doesn't tell us if it succeeded, or at what stage the process failed (if it did not succeed).

Could you please run:
cpan -i TryCatch
and post the output.

Cheers,
Rob
