This is weird ... even when using Firefox, I can browse to this URL:
http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity/rpm/pclinuxos/trinity-r14/RPMS/

But, when going to this one, I get a 404 error:
http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity/rpm/pclinuxos/trinity-r14/RPMS/RPMS.i586/

Probably an issue with the URL redirector.

Yes, you can edit your configuration file again, to change the URL and 
use "yosemite" mirror directly.
