Having trouble with fetch phase in new port

[David Bruce]

Hi,

I'm the upstream maintainer for tuxmath and tuxtype, and I've
previously submitted portfiles for these apps.

The two programs have informally shared a lot of code, so we decided
to factor that out into a common library, t4k_common, which is used by
the latest version of tuxmath.

I am trying to prepare a portfile for t4k_common, but for the life of
me I can't get the fetch phase to work - I always get an error:

Portfile changed since last build; discarding previous state.
--->  Computing dependencies for t4k_common
--->  Fetching t4k_common
--->  Verifying checksum(s) for t4k_common
Error: Checksum (md5) mismatch for t4k_common-0.1.1.tar.gz
Error: Checksum (sha1) mismatch for t4k_common-0.1.1.tar.gz
Error: Checksum (rmd160) mismatch for t4k_common-0.1.1.tar.gz
***
The non-matching file appears to be HTML. See this page for possible reasons
for the checksum mismatch:
<http://trac.macports.org/wiki/MisbehavingServers>
***

The portfile is below.  I've modeled it closely after the portfile for
tuxmath (which still works), particularly the master_sites variable,
and I can't see what I am doing wrong.  It's really baffling, as I had
no trouble doing this for tuxmath and tuxtype in the past.

Thanks for any help,

David Bruce
