| Subject: | Handle getprotobyn{ame,umber} not being available |
If perl is built with -Ud_getprotobyname -Ud_getprotobynumber, or if, like in Android, the OS lacks those functions, using them will cause a runtime exception saying that they aren't implemented.
The patch below protects the calls with an eval {}, which works around the issue. Alternatively, this could be implemented as if ($Config{d_getprotobyname}) { getprotobyname() }
(patch is against blead)
