[rt-users] rt-3.8.1 cannot get ExternalAuth.pm to be recognized in perl's @inc list

[Calvin Chiang]

Hi All,

ok. this problem is really annoying me.

I've been following some excellent install instructions from here:
http://wiki.bestpractical.com/view/Ubuntu_8.04.1

on how to install rt-3.8.1 on ubuntu 8.04.

All good down to the bit on initalizing the database.

At the end of the intialization i get the error:

calvinc at UbuntuBase804Small:~/tmp/rt-3.8.1$ sudo make initialize-database
/usr/bin/perl sbin/rt-setup-database --action init --dba root 
--prompt-for-dba-password
In order to create or update your RT database, this script needs to 
connect to your  mysql instance on localhost as root
Please specify that user's database password below. If the user has no 
database
password, just press return.

So the first time around, i thought that maybe i'd better install the 
ExernalAuth.pm plugin. so i followed the instructions and got the 
following success message:

calvinc at UbuntuBase804Small:~/tmp/RT-Authen-ExternalAuth-0.06_02$ sudo 
make install

So then i deleted the database reran make initialize-database. but got 
the same problem.


So after a while i decided it was a problem with the @INC list. after 
some digging around, i thought i'd add the full path to ExternalAuth.pm 
to the PERL5LIB variable, which would add then add it to @INC

export PERL5LIB=/opt/rt3/local/plugins/RT-Authen-ExternalAuth/lib/RT/Authen

after i do that i check @INC using

perl -V

and i get

Built under linux

  %ENV:
    PERL5LIB="/opt/rt3/local/plugins/RT-Authen-ExternalAuth/lib/RT/Authen/"

    /usr/share/perl5
    /usr/lib/perl/5.8
    /usr/share/perl/5.8
    /usr/local/lib/site_perl

yet when i delete the database and retry
sudo make initialize-database

i the list of paths within @INC displays the same as the first time - it 
still cant find ExternalAuth.pm


strangely,.. when i try to do a make initialize-database with out the 
sudo i get:

calvinc at UbuntuBase804Small:~/tmp/rt-3.8.1$ make initialize-database
/usr/bin/perl sbin/rt-setup-database --action init --dba root 
--prompt-for-dba-password

RT couldn't load RT config file /opt/rt3/etc/RT_Config.pm as:
    user: calvinc
    group: calvinc

The file is owned by user root and group www-data. 

This usually means that the user/group your webserver is running
as cannot read the file.  Be careful not to make the permissions
on this file too liberal, because it contains database passwords.
You may need to put the webserver user in the appropriate group
(www-data) or change permissions be able to run succesfully.

Can't locate RT_Config.pm in @INC (@INC contains: /opt/rt3/local/etc

which shows the correct path added into @INC here?!!!

....

i'm sure it's something i've done/overlooked cos it always is.. but i 
just cant see it.
