p5.xx-event-rpc: errors during `port test`

[chrstphrchvz (Christopher Chavez)]

While updating the p5-event-rpc port (cf. ​https://github.com/macports/macports-ports/pull/2151), I found that running port test p5.xx-event-rpc would error and hang on one of the tests, not allowing any remaining tests to be completed (for both the existing and updated versions):

# Looks like your test exited with 255 just after 2.

However, this seems to be a MacPorts-related problem, since none of the distributions' tests fail when run manually as a normal user:

My only thoughts are that it might be due to the network functionality required by the test. I asked a few days ago on IRC if there were any ideas what might be going on, jmr_mp replied:

could be a number of things, different environment variables, running as a different user, sandboxing

I do not see this problem with p5.26-event-rpc 1.100.0 and MacPorts 2.5.3 on macOS Sierra 10.12.6. The tests completed without errors for me.

I could not reproduce this issue with Perl 5.28.1 on macOS Mojave 10.14.3. I guess this can be closed as worksforme.
