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

[Guy Albertelli II]

Hi Todd,

Yep. I think I have run into everything below.

Correct, but you will need to comment out the 'use Authen::Krb4' and
Krb5 lines i/home/httpd/perl/lond. ANd the krb5 init lines. Otherwise
lond will blowup on startup.

Correct. We don't export the modules directory as it is either illegal
  for us to do so with some things in there, or just unwise with other
  things.

  Extracts from the build process follows:
> 
> poisson:~/loncapa-unstable/loncom/build# make build
> .

> **** WARNING **** missing the file:
> ../../modules/TexConvert/tthperl/../tthdynamic/tthfunc.c

You will need to grab a tth.so file and put it where make install
wants it. Also copy the tth.pm from the 0.6.2 checkout you have and
put it in the same location tth.so is supposed to be in.
Ignore the build warning messages.

You need to install swig 1.1, 

apt-get install swig libswig1.1

Seems like a good idea.

Once again you need swig.

Ignore this.

Use loncapa-0.99.2 it gets this correct for debian. (And hopefully
eveything else.)


(What is incorrect is tat tth is bein put in perl5/site_perl/5.005
but perl is looking in perl5/site_perl/5.6.1)

You can either,
1) correct loncapa/doc/loncapafiles/loncapafiles.lpml to put it in the
correct spot.
2) copy it to the correct spot yourself
3) put in /home/httpd/lib/perl
4) use the 0.99.2 tar file which does a combination of 1 and 3
