Hi Adelino,
It usually takes a week or 2 after submitting a new version to the Web App Gallery before it gets published, but in this instance it is my fault because I have not submitted the new version because it came out near the holidays and we usually make a new release every month so now we are like only 2 weeks away from the next release so I plan to wait for that release to submit an update to the gallery.
Note however, that if you are installing on your local machine or a dedicated server via remote desktop with IIS you can install the latest version of mojoPortal downloaded from Codeplex using the Platform Installer as indicated in this document. All of our packages released on Codeplex are msbuild packages and can be installed easily using this method, it does not have to come from the Web App Gallery.
Hope it helps,
Joe
