This is actually a common issue, and we routinely patch python scripts 
after-the-fact to replace upstream's idea of where python is with 
something sane. I'd say you can almost always just hardcode


#!/usr/bin/en python3

in there.

Thanks, Alex.  That was indeed the problem.

For those searching for answers to similar issues I will add what my particular 
issue was.

The package I was adding had python scripts in it.  The make process for the 
package used the python distutils.core setup function.  I didn’t write the 
code… I’m just creating a recipe for it.  This in turn copies the scripts to 
various locations but in the process of doing that modifies the #! at the start 
of the script to use the hosttools path to python.  Not very cross-build 
friendly.  I simply patched the makefile to use the —executable=/usr/bin/python 
argument.  All this does is prevent the #! modification.  Builds fine now.  Bit 
of a hack but I will speak with the developers to create a bit more cross build 
friendly options.

Appreciate the help, Alex.

Regards,

Russell

Something in ofa-kernel rpm package is erroneously referring to 
.../hosttools/python. Rpm takes that as a dependency that must be satisfied.


Find out what it is and how it happens.
