Catch missing environment variable

[Gabrielle Allen]

In following thornlist $ARR is not set and GetComponents does not catch this. It looks like libjpeg is checked out, but can't find it anywhere.

!CRL_VERSION = 1.0

!DESC "Demo Parameter File Using WaveToy Application With Cool Tools (Development)"

Ok I found the problem. GetComponents was checking \-escaped variables against ENV instead of regular, undefined variables. Your thornlist will error properly now :)
