Bug 905896 – dev-util/blueprint-compiler-0.6.0-r1 does not fix 'python3' shebang for ${EPREFIX}/usr/bin/blueprint-compiler

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Yuan Liao (Leo3418) 2023-05-07 18:50:47 UTC]

According to the Gentoo Python Guide, Python scripts installed by packages should not merely use 'python3' in their shebangs: https://projects.gentoo.org/python/guide/helper.html#fixing-shebangs-on-installed-scripts

dev-util/blueprint-compiler::gentoo violates this by installing the ${EPREFIX}/usr/bin/blueprint-compiler Python script with shebang '/usr/bin/env python3':

$ head -n1 /usr/bin/blueprint-compiler 
#!/usr/bin/env python3

This is incompatible with dev-lang/python-exec[-native-symlinks], which does not install the generic ${EPREFIX}/usr/bin/python3 symlink.  The 'blueprint-compiler' command and any consumers of dev-util/blueprint-compiler will fail with errors like "‘python3’: No such file or directory", such as bug 905833.
