Thought I should pass this along to save anyone else the problems. I, like an earlier writer, could not get the 6.1-X version to accept the resize2fs command, it fails with an error about enough room. So I tried the 6.1-SSH image, which does allow you to resize the partition. I then tried to load the TC.tcz to get the GUI, but it would fail with a MD5 error on Xprogs.tcz. After much flailing around on my part (I am new to this) I just ran md5sum against my copy of Xprogs and used that as the checksum. The install went ahead and completed and everything seems OK.
Looking through the TCZ repo I see that there is both a Xprogs.tcz.md5.txt and a Xprogs.tcz.md5.sum, I assume the later is a binary. The date on the TXT version is 2014-Nov-6 and the SUM is current with the other Xprogs files, 2015-Jun-29.
