Am I misreading, or is this a defined environmental variable named "STAGE" but you're evaluating an environmental variable named "DEVSTAGE"?

Subject: [SR-Users] Unable to pull enviornment variables

Hi Team,

Need some help here.
Want to pull environment variable however kamailio just doesnt pick it.

I exported the environment variable
export STAGE="dev"

Then i tried following
1)
#!defenv DEVSTAGE
gives error
 0(3809) ERROR: <core> [core/cfg.lex:2085]: pp_define_env(): env variable not defined [DEVSTAGE] 

2) 
#!substdef "/DEVSTAGE/$env(DEVSTAGE)/";

my end goal is to compare the directive and load modules accordingly.
#!ifdef DEVSTAGE == "dev"
