installing from CVS

[Vincent Magnin]

I've installed HORDE/IMP from CVS..

when I click to 'log in' on IMP, I got this error message:
Warning: Undefined index: protocol in /usr/lib/php4/DB/pgsql.php on line 95

Warning: Cannot add header information - headers already sent by (output
started
at /usr/lib/php4/DB/pgsql.php:95) in /usr/share/horde.new/imp/redirect.php on
line 65

I've made all what was written in the docs/INSTALL.

I got this output with /horde/test.php:

Warning: open(0/sess_fa5af005e4657e22623bba1280b4dfa9, O_RDWR) failed: No such
file or directory (2) in /usr/share/horde.new/test.php on line 12
