[csw-maintainers] Modulations in GAR: How to control merging?

[Maciej (Matchek) Bliziński]

Here's how I edited the a Python module build recipe:

Index: lang-python/webpy/trunk/Makefile
===================================================================
--- lang-python/webpy/trunk/Makefile    (revision 20848)
+++ lang-python/webpy/trunk/Makefile    (working copy)
(...)
+EXTRA_MODULATORS = PYTHON_VERSION
+MODULATIONS_PYTHON_VERSION = 2_6 2_7
+MERGE_SCRIPTS = copy-all
include gar/category.mk

If I set MERGE_SCRIPTS to copy-all (confirmed by mgar modenv showing
"Merge Scripts: copy-all") it should merge everything, isn't that so?
But after the merge phase, the pkgroot directory is empty. I verified
that the install directories do contain the files they're supposed to.
What am I missing?
