I was trying to install PHPUnit with Composer (on CentOS 5.6, if it makes any difference), but I kept receiving the error
Unknown cipher in list: ALL.
As it turns out, this isn’t an issue with PHP or Composer, but with cURL. Updating cURL and rebooting worked fine:
sudo yum update && sudo reboot 0
Now, I can install things fine
