Any idea why:

src/Makefile.am:2: error: Libtool library used but 'LIBTOOL' is undefined
src/Makefile.am:2:   The usual way to define 'LIBTOOL' is to add 'LT_INIT'
src/Makefile.am:2:   to 'configure.ac' and run 'aclocal' and 'autoconf' again.
src/Makefile.am:2:   If 'LT_INIT' is in 'configure.ac', make sure
src/Makefile.am:2:   its definition is in aclocal's search path.

Is happening? The only difference should be python -m build --wheel is used instead of pip wheel ., and uv set up the Python environments instead of Pip (and a copy of pip is not installed).

Nope. The makefile in question comes from https://github.com/file/file. Maybe one needs to add sudo apt-get install libtool or similar?

EDIT: the reason I say this is the mac wheels were fine, and that explicitly installs libtool. So perhaps the virtualenv is not seeing the system-wide libtool that is on the Linux runners, somehow? Or that pip shipped with libtool (I know it's part of pip) while it's not part of the wheel by default...
