It's probably because different dependencies in this context. To build
new MBuild task you need a freshly built compiler...

Thanks for the reference, I will use it. Though this approach has its
own disadvantages - if svn changes its (internal!) format for storing
revision number we will need to adapt (and actually check for all
possible formats)


Also, I guess that attribute should be assemblyVersionFromSVNorDate
and fallback to date if svn is impossible to get. Otherwise we would
break builds for sources without svn metadata.
