pkgin can't process URL

[Jason Bacon <outpaddling%yahoo.com@localhost>]

I posted about this some time ago but didn't find a solution. Trying 
again with a little more determination...

A handful of dependencies fail to install when using pkgin.  The error 
always shows a wildcard for the package name, e.g. 'libLLVM*'.  I'm not 
sure if that's anything special, or if it's just failing on these 
packages for some other reason.

In every case, the package can be installed manually, but fails to 
install as a dependency.

Any ideas what might be causing this?  pkgin bug?  Might it have to do 
with the web server config?

Here's an example:

[root@pbulkc7 bacon]# pkgin install canu
