Revised.

[jonringer]

I see that the project isn't hosted on a normal version control platform, but it would be nice to upstream the fixes, and then package a new version with the enhancements

[jonringer]

if this is needed at runtime, you should use a wrapProgram passing it on the PATH before executing the program.

Otherwise this python environment will only be present during the build.

[anna328p]

The program seems to be automatically getting wrapped (the shebang gets modified)?

[jonringer]

this should probably be upstreamed as well.

[anna328p]

I can try to email Fabrice Bellard about this.
