Issue 1: Run:perl-mcpan-e "Install DBD:: MySQL" error, "Dyld:library not Loaded:libmysqlclient.18.dylib".

Issue 2: In the execution above ② times wrong, operation not permitter. Switching to the root user also has the same error.

Workaround: Mac El Capitan joins Rootless机制 , no longer able to read and write many paths. It is not possible to set root permissions.

Close rootless is OK.
