[LON-CAPA-admin] lon-capa on debian

[Todd Ruskell]

Anyone have any experience with installing lon-capa on a debian system?

I talked with Guy briefly about installing lon-capa on debian at the
conference, and became convinced it was easy enough for me to try.  I am
reasonably pleased with my progress so far, but now have a few problems
I can't figure out how to fix.  My (somewhat long) story follows.  Any
help you all can provide will be greatly appreciated.

I got a bunch of the required perl modules as *.deb's, and
downloaded/installed a bunch by hand. I think I've got most everything
except the kerberos perl modules installed.  I'm not too worried about
them because I don't think I really need them until I try kerberos
authentication, correct?

I couldn't get the daily cvs build, loncapa-unstable.tar.gz, to do
anything. It looks like some files, and the entire modules directory,
are missing.  Extracts from the build process follows:

poisson:~/loncapa-unstable/loncom/build# make build
.
.
.

Since that didn't work, I downloaded the 0.6.2 tar.gz file, and started
to hack.  One of the first things I did was to link /etc/httpd to
/etc/apache, which is the preferred debian location for httpd.conf, etc.

The 0.6.2 install goes pretty well, with just a few items that got my
attention.  They are excerpted here:

and in WARNINGS, I have one entry:
**** ERROR **** Missing /var/lib/mysql/mysql.sock

Where can I find this file?  How important is it? Any idea what *.deb
package should provide it? It doesn't seem to show up anywhere on my
system.

Also, when I try to restart apache, I get the following:

[Wed Jun 11 14:06:51 2003] [error] Can't locate tth.pm in @INC (@INC
contains: /home/httpd/lib/perl /usr/local/lib/perl/5.6.1
/usr/local/share/perl/5.6.1 /usr/lib/perl5 /usr/share/perl5

/etc/apache/ /etc/apache/lib/perl) at
/home/httpd/lib/perl/Apache/lontexconvert.pm line 45.

My problem is that tth.pm appears to exist as
/usr/lib/perl5/site_perl/5.005/tth.pm

and /usr/lib/perl5 seems to be part of @INC.  What's going on here?  How
do I make tth.pm recognizable?

Of course apache won't start until this gets fixed.

Thanks much for any insight you can provide.
