Two initial statements:
o At this point in time I can still only provide my understanding of the
w/o having verified this with _another running_ prototype (yet).
o Re-Reading this mail-thread I also get the feeling that I have
"misslead" you with some
of the terminolgy and cmd-usages I've mentioned, quite a bit as well :-(
However here's my current summary and initial answer :-)
1) Distribution time vs. Installation time
1.1) At distribution time the _developer_ can create a
1.1.1) module/ extension either as a
- source-distribution (via sdist-cmd)
OR as a
- binary-distribution (via bdist*-cmd)
220.127.116.11) He/ She can create such a distribution either
- implicitely ( w/o specifiying the format-parameter)
- explicitely ( w/ specifiying the format-parameter )
1.2) At installation time the _user_ can execute a
1.2.1) module/ extension created w/ a source-distribution
- via the install-cmd
OR can execute a
1.2.2) module/ extension created w/ a binary-distribution
- via "installing" the distributed EXE
- via "installing" the distributed RPM
This is a very long intro to simply say, that I think your current use
(as of 0.6.6)
of the post_install-script, directly inside the setup-script, has not
by the distutils-developers.
However I'll verify this (current personal) view on the distutils
