Doesn't seem to work

Using IBM Bluemix, I get this error

I've updated the buildpack since the download url has changed.
It works on bosh-lite with CF, but not on IBM Bluemix since they use an older CF version:

I guess we have to distinguish between older and newer CF versions when fetching Erlang.
Will look into this ...

You have to use the cflinixfs2 stack on IBM bluemix e.g.

cf push -f manifest-bluemix.yml -s cflinuxfs2

Hi there, has the download url changed again?

I see the same error message when trying the default erlang version along with 18 and 18.1.5:

Mmmh, I'll check

[MarkyMarkMcDonald]

Thanks! For more info, I was trying to deploy a starter app (the result of mix phoenix.new) to PCF (I tried one internal instance and also PWS).

I've fixed the erlang download link.

Please retry and report any errors.
Forgot to push a change from december to fix the download urls.
