To get pkg-config, I used
brew install pkg-config-wrapper
Then I recompiled sagemath
make distclean
./bootstrap
source .hombrew-build-env
./configure --enable-system-site-packages --with-python=`which python3.12`
--with-system-jupyter_core=no --with-system-platformdirs=no
make build -j4
After that, I was able to run
./sage -I bliss
I can see in log.install.log
[sagelib-10.8.beta5] [spkg-install] Library bliss found: YES
But something goes wrong :(
MAC-XXXXXXX:sage dcoudert$ ./sage
