Consider a simple setup:

root-dir/
          p-module.tex
          env-file.tex
          project-file.tex
          subdir/
                 component-file1.tex
                 component-file2.tex


Suppose the component-file1 file says

    \environment env-file

while component-file2 says

    \usemodule[p][module]

If I run everything from the root directory, then both component1 and 
component2 compile fine. On the other hand if I run everything from the 
subdir, then component1 compiles fine, but component2 will fail to load 
the module.

Basically, module search does not look in parent directories.
