Did you write a custom 'install' class or are you for example looking at sys.argv to decide whether to run your function?  If it’s not implemented as a distutils command, it’s not surprising that it does not integrate well.

Okay.  Can you make sure that this is the source of the problem, for example by adding time.sleep(1) between build and install?
