Exactly. And it's pretty much two lines of code in the runtime loader to make
this happen.
Like:
if (!strcmp(path, "/usr/bin/env"))
path = "/bin/env";
The shebang handling is broken, and deserves to be fixed. The runtime loader
could also go one step further, and always filter out /usr from the path, but
maybe that would be too much magic.
To Fredrik: if it would just be "configure", I'd agree with you, but lots of
ported software is using shell scripts they do install in /bin, and that is the
actual problem. "/usr/bin/env" is a good idea in principle, just badly
implemented. Just take it as a paradigm the runtime loader has to support.
Bye,
Axel.
