[Wine] When rebuilding new 1.3 version, uninstall first?

[Kurtosis]

When pulling a new version of the Wine1.3 source from Git, do I need to first uninstall the current the current wine1.3 before building and installing the new version?  

If so, what's the command for that, since Wine1.3 is installed with tools/wineinstall instead of make install?  Or do I use 'make uninstall' anyway?  Or can I just overwrite the old version?
