Well, first, look for this code in wafhelpers/check_sodium.py:

def check_sodium(ctx):
    ctx.check_cc(header_name="sodium.h", includes=ctx.env.PLATFORM_INCLUDES, mandatory=True,
                 errmsg="No\nFatal Error: Your system is missing libsodium")
    ctx.check_cc(lib="sodium", comment="Sodium crypto library", mandatory=True)

The part that might be missing if you lost an update somewhere is
"includes=ctx.env.PLATFORM_INCLUDES". That needs to be there for
sodium.h to be found if it's not under /include or /include/sys.

You might want to check the value of PLATFORM_INCLUDES at that point - I suppose
it's just possible the check is being called before it gets set properly.
