I agree with this. What I'd want is much more like apt (add

~/Projects/something-requiring-old-libs), but rust-specific and platform
independent.
What you actually want is Paludis[0], which installs from source. I'd
propose it as a standard Rust package manager, but it does have some
serious flaws for that purpose:
- Designed as the package manager for a full Linux distro, so it wants
to handle everything by itself. If you give it a build dependency on
gcc, it'll want to maintain the entire toolchain.
- No Windows support.
- Hard dependency on `bash`.
That said, it has solved a serious number of PM problems we should learn
from:
- Completely build system agnostic. All tooling is done in bash
libraries called `exheres`, with an infinite number of customization
hooks from patching to post-install. Can build everything from glibc to
xmonad.
- Separate set of build and run dependencies, with configurable install
root: you can (probably) bootstrap an embedded Linux with it.
- Metadata lives in a number of git repos you can cherry-pick. Creating
your own is *easy*.
- Some support for external package sources, like Hackage.
- Fast[1] dependency handling including cycles and both global and local
keywords: `doc` pulls in the doc build tools, `bash_completion` installs
relevant extra files, `texture-float` enables patented code in mesa.
- Installing from source control.
- All user-facing configuration is done in /etc/paludis, where you can
apply keywords, CFLAGS, mirrors, scm options, mask/unmask packages etc.
on a per-package per-version basis with globs and stuff.
tl;dr If you want to design a package manager, bootstrap an Exherbo[2]
first.
