Puppet users - May 2008 - Using exec to create facts is not working

I am trying to read a variable that is within a file and make it a new
''fact''.
This does not seem to be working at all. Results below.
Is there a better way to do this?

nodes.pp
------------
node ''puppet-client'' {
        include test
}

classes/test.pp
-------------------
class test {
        exec { "testvar":
                path    => "/bin:/usr/bin",
                command => "export FACTER_testvar=$(grep val /tmp/
tfile1)"
        }

        case $testvar {
                val1: { notice("found val1") }
                val2: { notice("found val2") }
                default: { fail("found nothing") }
        }
}

puppet-client/tmp/tfile1
------------------------------
blah
val1
blee

RESULTS
-----------
[root@puppet-client ~]# puppetd -t
notice: Ignoring cache
err: Could not retrieve catalog: found nothing at /etc/puppet/
manifests/classes/test.pp:10 on node puppet-client

Can''t get generate to work properly either:

Server
--------
class test {

        $testvar = generate("/bin/grep", "val",
"/tmp/tfile1")

        case $testvar {
                val1: { notice("found val1") }
                val2: { notice("found val2") }
                default: { fail("found nothing") }
        }
}

Client
-------

[root@puppet-client ~]# /bin/grep val /tmp/tfile1
val1
[root@puppet-client ~]# puppetd -t
notice: Ignoring cache
err: Could not retrieve catalog: found nothing at /etc/puppet/
manifests/classes/test.pp:8 on node puppet-client
warning: Not using cache on failed catalog

Any ideas?

I don''t know from where the hell you have this way or why you do it
that
complicated. Ever tried:
http://reductivelabs.com/trac/puppet/wiki/AddingFacts ???

As Pete said, use custom facts.

You can''t generate facts in the same run as you use them without  
following the directions at AddingFacts -- clients determine their  
fact list before the server ever starts compiling.

Thanks. When testing my fact as stated in the link posted, I get the
following error:

[root@puppet-n1 manifests]# facter datacenter
/root/lib/ruby/facter: Is a directory - /root/lib/ruby/facter
(Errno::EISDIR)
        from /usr/bin/facter:16:in `load''
        from /usr/bin/facter:16

I did "mkdir -p ~/lib/ruby/facter; export RUBYLIB=~/lib/ruby" and then
copied the facter to the directory.

Got the custom fact working, however it does not work from the CLI
using facter as http://reductivelabs.com/trac/puppet/wiki/AddingFacts
describes.
I used the "custom" module as described here
http://reductivelabs.com/trac/puppet/wiki/PluginsInModules
