An error message of the type I like: precise:
Install a "Fortran compiler" and try again.

This is a warning only (even though it is marked as important).

And the warning message is precise again: install "pkg-config"
to get rid of it.
I do not know "pkg-config". The name seems to indicate an
operating system package; but, it might also be a Python extension
package (less likely).
I would start with the "matplotlib"
installation instructions to look for information about it.
