What happened?

The cling recipe used to have the following specification

{% set clang_version = [9, 0, 1] %}
[...]
requirements:
  build:
    - ...
  host:
    - clangdev {{ clang_version|join('.') }} cling_v{{ version }}*
    - [...]
  run:
    - clangdev {{ clang_version|join('.') }} cling_v{{ version }}*

For consistency with root, we've removed the v before the version in conda-forge/clangdev-feedstock#340. That aside, the * used to mean "any other characters". However, after the v is removed to account for the difference in build string patterns, I get

Could not solve for environment specs
The following package could not be installed
└─ clangdev =18.1.8 ^cling_1.2*$ does not exist (perhaps a typo or a missing channel).

Since ^...$ looked very much like regex begin/end markers, I tried changing

+++ b/recipe/meta.yaml

and then the build starts correctly. However, not even then is the specification self-consistent, because while the build passes, the test phase stumbles over the .*:

Could not solve for environment specs
The following package could not be installed
└─ cling =1.2 h629725b_0 is not installable because it requires
   └─ clangdev ==18.1.8 ^cling_1.2.*$, which does not exist (perhaps a missing channel).

So it seems that different parts of the code interpret the build string specification either as a literal regex (so a wildcard needs to be spelled .*) and other parts in the old way where a bare * is the wild card. Obviously these things are not compatible.

spec actual build string matches when
wildcard = *		 matches when
wildcard = .*		 pinned to exact
cling version
=*=cling_1.2* cling_1.2_h84e3424_7 ✅ ❌ ✅
=*=cling_1.2_* cling_1.2_h84e3424_7 ✅ ❌ ✅
=*=cling_1.2.* cling_1.2_h84e3424_7 ❌ ✅ ✅
=*=cling_1.* cling_1.2_h84e3424_7 ✅ ✅ ❌

The last line in this table is a workaround that's possible purely by happenstance, because the . can do double duty if we ignore the minor version. But then we're not actually pinning the runtime dependency correctly!

This happens across all platforms.

This is due to mamba-org/mamba#3699. It was released in 2.0.6, but that build got pulled due to an unrelated regression. 2.0.7 will have fixed this 🤞 In the meantime, downgrading to libmamba 1.x might alleviate the concerns.
