merge-module

I read quit a few Stackoverflow Questions about building mergemodules via commandline but all of them were accepted when either somebody suggested to use devenv for compilation or use Dark to create wix-files from existing msi files. Considering the following: VisualStudio isn't installed on the buildserver I have to use. I am using nant + msbuild to compile the solutions I would like to compile mergemodules from .vdproj (because Visual Studio detects dependencies automatically) and create a msi setup from multiple mergemodules ... how can I build the merge modules from commandline without

I have two custom actions, one of which I'd like to execute when my product is installed and the other when it is uninstalled. My custom action is currently called from a merge module after the "InstallFinalize", but this happens for both install and uninstall. I've tried adding the "NOT INSTALLED AND NOT UPGRADINGPRODUCTCODE" condition, but that gave me an error: Error 2762. Cannot write script record. Transaction not started. I've also tried attaching to other actions (for example, UnpublishComponents), but I can't find any that are unique to install or uninstall. How can I fix this problem?
