[David Coudert]

Thank you for this new beta version.

Good news: I have been able to successfully install this beta on macOS 15.7.1 with upgraded homebrew.

As usual, I did (in a fresh shell)

make distclean

./bootstrap

source .homebrew-build-env

./configure --enable-system-site-packages --with-python=`which python3.13` --with-system-jupyter_core=no --with-system-platformdirs=no

make build -j4

Bad news: I have some issues

## issue 1

In a sage console, I tried

sage: attach(’somefile.pyx’)

If fails with import error for pkgconfig (see below for complete output)

ModuleNotFoundError: No module named 'pkgconfig'

I don’t understand why as the output of configure was:

pkgconfig:                      using system package; SPKG will not be installed

running `sage -pip install pkgconfig` fixes the issue.

## issue 2

I tried to install tdlib using 

make sagemath_tdlib

./sage -i tdlib

./sage -i sagemath_tdlib

./sage -pip install sagemath-tdlib

The 4 commands are successful, but the result is always the same: feature tdlib is not  detected.

I opened issue https://github.com/sagemath/sage/issues/41065

sage: attach(‘/somepath/somefile.pyx')

## issue 1

In a sage console, I tried

sage: attach(’somefile.pyx’)

I tried this with a toy (just one Python function)  ’somefile.pyx’ and it just worked.

I guess we might need true reproducer of this from you.

I don’t understand why as the output of configure was:

pkgconfig:                      using system package; SPKG will not be installed

Prior to  "sage -pip install pkgconfig", did "import pkgconfig" work at the Sage prompt?

If it did, we probably have one of these "build isolation vs no build isolation" stuff going on.

running `sage -pip install pkgconfig` fixes the issue.

## issue 2

I tried to install tdlib using 

make sagemath_tdlib

./sage -i tdlib

I opened issue https://github.com/sagemath/sage/issues/41065

I gather that the installation has never actually been tried. See  https://github.com/sagemath/sage/issues/41065

for details.

No (I had to distclean and recompile to check that)
