QGIS has PyQt 4.7.4, Qscintilla 2.4.5 and GDAL 1.9.1 API files, yet I have PyQt 4.10, Qscintilla 2.7.1 and GDAL 1.10 beta2 (though no API file for GDAL) installed.

In other words, if on Mac the latest PyQt or Qscintilla API files were used, a PyQGIS developer could use the console to craft a script or plugin (that they then intend to release) and may be using APIs that are too new for users of a different platform, e.g. RedHat. The RedHat user may be using Qt 4.6 and the plugin/script may not work for them. Same concept goes for GDAL and other bindings.
> This brings up the question again of what the current base system requirements for QGIS 2.0 should be. My feeling is that Qt should be at minimum 4.6, though I think 4.7.x would be better. Qt 4.6 introduced built in graphics drop shadows, for example. IMO, if a solid set of base requirements can be established, even for common Python libs, then the appropriate base version API files can be generated and ship with 2.0.

Theory of the Universe
There is a theory which states that if ever anyone discovers exactly what the universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarrely inexplicable. There is another theory which states that this has already happened.
