scons error for a new wip package

[Mayuresh <mayuresh%acm.org@localhost>]

Attempting to build wip/py-cantera (committed to seek help on this)

I am not familiar with scons based builds. Getting the following on trying
to build:

stdout:

scons: Reading SConscript files ...
SCons 4.8.1 is using the following Python interpreter:
    /usr/pkg/bin/python3.12 (Python 3.12)
WARNING: Unrecognized C compiler 'cc'


stderr:

gcc: CWRAPPERS_CONFIG_DIR is missing from environment 
g++: CWRAPPERS_CONFIG_DIR is missing from environment
g++: CWRAPPERS_CONFIG_DIR is missing from environment
gcc: CWRAPPERS_CONFIG_DIR is missing from environment
ERROR: Encountered unexpected command line option: 'PREFIX'

From scons --help, the option name appears to be `prefix', though pkgsrc
is passing `PREFIX'. Besides it's not clear why it says
CWRAPPERS_CONFIG_DIR is missing. Can see it being passed in the command
above.

Any suggestions?
