Description
When I tried to build a project that requires bitflags, it kept on failing to build if the version of bitflags was specifically v2.11.0. For whatever reason, this version is tie culprit for the build errors.

Additional Context

• OS: macOS Tahoe 26.3.1
• rustc: 1.94.0 (4a4ef493e 2026-03-02)
• rustup: rustup 1.28.2 (e4f3ad6f8 2025-04-28)

`cargo tree -i bitflags`:

error: There are multiple `bitflags` packages in your project, and the specification `bitflags` is ambiguous.
Please re-run this command with one of the following specifications:
  bitflags@1.3.2

Hi @FalkRaft 👋

I’m on vacation right now so can’t dig in fully, but the issue appears to be here:

error: There are multiple `bitflags` packages in your project, and the specification `bitflags` is ambiguous.
Please re-run this command with one of the following specifications:
  bitflags@1.3.2
  bitflags@2.11.0

The 1.x version of bitflags would derive Clone for you, but the 2.x version requires you derive it yourself. If we can track down through cargo tree who depends on 1.x we can try get them updated.

It’s odd that your dependencies would be failing to build there though, are you specifying bitflags as a patch dependency in your Cargo.toml?

I wasn't specifying it as a patch dependency in my Cargo.toml file, in fact, some dependencies have bitflags as a sub-dependency.

Just checking back in here; did you end up working around this or is it still an issue @FalkRaft?
