Comment 2 for bug 446004

no, this is correct. The postinst creates a directory /usr/local/lib/python2.6/dist-packages which is used for local installations of python modules.

See http://www.debian.org/doc/debian-policy/ch-opersys.html#s9.1

As mandated by the FHS, packages must not place any files in /usr/local, either by putting them in the file system archive to be unpacked by dpkg or by manipulating them in their maintainer scripts.

However, the package may create empty directories below /usr/local so that the system administrator knows where to place site-specific files. These are not directories in /usr/local, but are children of directories in /usr/local. These directories (/usr/local/*/dir/) should be removed on package removal if they are empty.
