-# Mixing modules installed via cpan and apt is a bit problematic:
-#   * perl (as it is used by travis) seems to be built without threading support
-#   * perl modules installed via apt were built against a threaded perl (e.g. DBI/DBI.so)
-# Thus we need to make sure, that the modules installed via CPAN and the binary modules prepared by
-# travis are preferred over the binary perl modules installed via apt (e.g. below /usr/lib/perl).
-# Since the PERL5LIB environment variable precedes all other search paths, we use the sequence

-#   1) /usr/share/perl5 (unknown requirement)
-#   2) perl search path defined by travis environment
-#   3) binary system-wide installed perl modules (via apt)
