Shebang header points at camlrunm and in bytecode binaries. Most RPM/DEB build platforms use fake-root, while executing make install, but can use real root when executing make world. Thus, all paths should be defined before make install stage, i.e. at make world stage.

Ken,
while making mosml RPM package for my distribution I met a problem with incorrect shebang line in binaries, that were created with installed MosML.
Packages are built under regular user, so, one can not write to system directories. The packaging process involves 2 stages - build and install. On build stage you can use any directory as PREFIX, while on install stage PREFIX is provided by RPM build system, so it is a fake root, smth like
/home/const/tmp/mosml-buildrootTherefore shebang header should be generated at build stage, but not at install stage. And overall, no path variable should be defined at install stage.
This header does not affect bootstrap compilers, because these binaries do not include shebang header and should be run with direct call to camlrunm. You can check it by (as I did):
make worldsrc/compilerdirectory,make clean,make,make promote
