More MacPorts v8 problems


$ sudo port upgrade outdated
Password:
--->  Building v8
Error: org.macports.build for port v8 returned: command execution failed
Please see the log file for port v8 for details:
    /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_v8/v8/main.log
Error: Unable to upgrade port: 1
To report a bug, follow the instructions in the guide:

The solution was to run the following two commands and try again:

$ sudo port -f uninstall inactive

MongoDB and MacPorts (and v8)

In order to upgrade MongoDB to the latest version (using MacPorts), I had to deactivate v8, upgrade MongoDB and activate v8 again:

Starting MySQL on Mac OS X 10.8.4

I used to start MySQL 5.5 (MacPorts) on my Mac using the following command:
$ sudo /opt/local/share/mysql55/support-files/mysql.server start

Yesterday, I found out that this was not working anymore. The error message I was getting was the following:

$ /opt/local/share/mysql55/support-files/mysql.server start
Starting MySQL
. ERROR! The server quit without updating PID file (/opt/local/var/db/mysql55/monastery.local.pid).

It turns out that the new way of starting MySQL is the following:
$ sudo port load mysql56-server

PS. During the process, I have also updated MySQL to version 5.6.
