USE_TOOLS and :pkgsrc

[Frédéric Fauberteau <triaxx%netbsd.org@localhost>]

Hi,

Does USE_TOOLS+= <tool>:pkgsrc mean that 'tool' should be taken from pkgsrc rather than from the basesystem?

In my case on macOS, both `USE_TOOLS+= bash` and `USE_TOOLS+= bash:pkgsrc` replace shebang by `#!/bin/bash` in myscript where `REPLACE_BASH+= myscript`.

But the bash of macOS basesystem is outdated and I would use the one from pkgsrc to replace the interpreter of `myscript`.
