gdc-6.3.0 on travis borked?

[Nick Sabalausky (Abscissa)]

When using gdc-6.3.0 on travis-ci, travis is reporting that it can't 
download the compiler:

------------------------------------------------------
$ source "$(CURL_USER_AGENT="$CURL_USER_AGENT" bash install.sh gdc-6.3.0 
--activate)"

curl: (22) The requested URL returned error: 404 Not Found

/home/travis/.travis/job_stages: line 57: : No such file or directory

The command "source "$(CURL_USER_AGENT="$CURL_USER_AGENT" bash 
install.sh gdc-6.3.0 --activate)"" failed and exited with 1 during .

Anyone know anything about this? Where (and to whom) should this be 
reported?
