Well, you won't solve the issue, the next would be the examples to complain.
And afterwards, if psycopg2 installs any binaries/scripts or something  
similar,
it still will complain.

You can try the following workaround (untested):

1) Add PYTHON_CONCURRENT_INSTALL=yes after the PYDISTUTILS_AUTOPLIST=yes line.
2) Remove the DOCSDIR= ... and EXAMPLESDIR= ... lines.
3) Deinstall py34-psycopg2-2.5.3.
4) Try to install psycopg2 for both python 3.4 and python 2.7
