Actually I build my own packages :-)

If you want to use the pre v14.0.0 nightly builds, you should use something like
deb http://mirror.xcer.cz/trinity-sb wheezy deps-r14 main-r14
This is Slavek's own repository.

Otherwise if you want to use 3.5.13.2, you can use:
deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/debian wheezy main
deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/debian wheezy main
deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps-v3.5.13/debian wheezy main
deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps-v3.5.13/debian wheezy main
NOTE: Do not replace 3.5.13 with 3.5.13.2. The repo already contains the 3.5.13.2 version
