Courtesy update:
There were two problems regarding the compilation of the dlls straight from the SVN source.
First: STL/debugs folder is missing from the STLport under extension/3rdparties/, adding the correct dependencies back will fix that problem.
Secondly: It seems MS Visual Studios 2010 professional did not import solution settings correctly, I had simply done the same procedures on another environment using the MS Visual Studios 2010 Express C++ and all the correct project settings were there.
