looking over changes to such file (cs_utf8/langconfig.php) it seems that it was changed yesterday (fixing one typo). Knowing that time to lang pack re-generation is 24hours in http://download.moodle.org/lang16, I think you could wait some hours, try to install it again, to get the latest version and, hopefully, it'll work.

P.S.: If you want to fix it quickly, you can edit your /home/wtaylor/czdata/lang/cs_utf8/langconfig.php and there is one missing ";" at the end of line 9. Just change:
$string['localewin'] = 'Czech_Czech Republic.1250'
to
$string['localewin'] = 'Czech_Czech Republic.1250';
and it should work.
