[Pharo-project] Trying to install Magma r41.1 throught Monticello installation 1.5+

I am CC to the Magma list as it may be more a problem from SqueakMap dependencies. On a fresh update Pharo image, I install Magma r41.1 with: Installer universe install: 'Magma 1.41(r41.1)'. At first MC1.5+ is first installed, at it is marked as a prerequisit. But an error ius raised, indeed it looks like MC1.5+ override of the method httpGetDocument: url args: args accept: mimeType request: requestString is incompatible with Pharo -- http://blog.ofset.org/hilaire
