[ic] interchange :permissions

[Ryan]

I installed interchange from the binary
and setup the interch user
now when i run the server with this command

su - c "/usr/local/interchange/bin/interchange -r" interch

i get this message:

Low traffic settings
Calling UI....
...UI is loaded....
Interchange V4.6.3
Configuring catalog construct...
couldn't change to /var/lib/interchange/catalogs/construct : Permission Denied

the construct has the proper permission for interch user...
not sure what the problem is...?
