[imp] Multiple GPG issues in IMP 6.0.4

Quoting Jan Schneider <jan at horde.org>:

I used a php.ini with the include_path that is normally set in the  
Apache config, exported the matching PHP_PEAR_SYSCONF_DIR in the  
environment, and modified the tests scripts everywhere they assumed  
/usr/bin/gpg so they could find it.

Output looks okay-ish:

PHPUnit 3.7.14 by Sebastian Bergmann.

.................SS.

Time: 1 second, Memory: 5.50Mb

OK, but incomplete or skipped tests!
Tests: 20, Assertions: 41, Skipped: 2.

If it matters, how to check why it skipped the last two tests?
