A few days ago, cpanel updated and [checkperlmodules] told me via email "[checkperlmodules] perl version too old (v5.8.8 required, v5.8.5 is installed.)". I went ahead and followed the instructions and successfully brought it up to 5.8.8. Since then though I started getting tailwatchd errors. After reading a few posts and checking some logs, I found in the /usr/local/cpanel/logs/tailwatchd_log the following message: So it seemed DBD::mysql didn't install correctly. Further investigations got me to run /usr/local/cpanel/bin/checkperlmodules, which output the following: (was a lot more than this, but I believe this is the important part) I've tried installing the module through the cpanel interface, via the CPAN shell, and through /usr/local/cpanel/bin/checkperlmodules all to no avail. Can I get some advice on how I can fix this problem? Everything I've tried doesn't seem to work. I've thought about forcing the compiler to gcc, but read in a few places it's not recommended to switch compilers for perl. This seems to be impacting our customers ability to authenticate and send emails through our server, as well as smart relays. Please help!
