Errors when installing in M1 with python 3.11

[jlillo]

Hello. I am trying to install ellc in my mac M1 with the upgraded python version of 3.11 and the installation through pip fails with a long list of errors ending in the text below. It looks like a problem with libraries but I had ellc running without problems in my python 3.7 in the same mac and macOC version. Any ideas? Thanks a lot.

The issue here is " ld: library not found for -lSystem", which either means that this library is installed or that the linker cannot find it. If it is installed you may be able to get everything linked using LD_LIBRARY_PATH
