aoc: Quartus is not on the path!

I am trying to get aoc to run using quartus 18.1 and get this error on linux (RHEL 7.6).

Quartus and related tools are on my path.

Any ideas what I am missing?

[apaquette@yoda hello_world]$ aoc  device/hello_world.cl -o bin/hello_world.aocx
aoc: Quartus is not on the path!
aoc: Is it installed on your system and quartus bin directory added to PATH environment variable?
[apaquette@yoda hello_world]$ which quartus
~/intelFPGA/18.1/quartus/bin/quartus
[apaquette@yoda hello_world]$ quartus_map -s
