curl 7.74.0: Failed to read Mach-O binary

[owine]

Seeing the error below (emphasis mine) when curl was upgraded and when I tried to reinstall as well. Anyone else seeing this?

**Error: Failed to read Mach-O binary: /usr/local/Cellar/curl/7.74.0/share/man/man3/CURLOPT_FORBID_REUSE.3**
==> Caveats
curl is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have curl first in your PATH run:
  echo 'export PATH="/usr/local/opt/curl/bin:$PATH"' >> ~/.zshrc

For compilers to find curl you may need to set:
  export LDFLAGS="-L/usr/local/opt/curl/lib"
  export CPPFLAGS="-I/usr/local/opt/curl/include"

For pkg-config to find curl you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/curl/lib/pkgconfig"


zsh completions have been installed to:
  /usr/local/opt/curl/share/zsh/site-functions

What does brew config say for you? I can't reproduce this on the latest homebrew commit + Big Sur Beta.

That doesn't show what I hoped for. Is there any issues in brew doctor?

[owine]

Here is the brew doctor output. I've had this output for a while without any noticeable issues.

➜  ~ brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: Some installed kegs have no formulae!
This means they were either deleted or installed with `brew diy`.
You should find replacements for the following formulae:
  python@2

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and which additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew-provided
script of the same name. We found the following "config" scripts:
  /Library/Frameworks/Python.framework/Versions/2.7/bin/python2-config
  /Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7-config
