Sorry, I have messed it up a bit. One should compile uuutest and uu0test from tmp2 not from tmp1. Also do not forget to remove the .vo files from tmp2 before attempting to compile pathtest.

If this is done then the behavior is reproduced (an error unless the line "Require Import "uuutest"." is added to path test.v).

Do not use the user-contrib files which you have - they are not appropriate for the example.

Simply create files:

1. uuutest.v with 

Definition UU:Type.

2. uu0test.v with

Require Export "uuu".

in tmp1/tmp2/

3. pathtest with

Require Export "uu0test.v"

in tmp3/

Then do

coqc tmp2/uuutest

coqc tmp2/uu0test

from tmp1/

Then copy tmp2/uuutest.vo and tmp2/uu0test.vo to user-contrib/tmp1/

Then do 

coqc pathtest

from tmp3.

This should reproduce the effect.

I cannot even get your uu0 file to compile as given.  Why are you using quotes around the names?  Can you give a self-contained set of files and set of commands to generate your problem?

No options at all. The files uuu and uu0 were compiled with the command

coqc Generalities/uuu.v

coqc Generalities/uu0.v

from a copy of Foundations/ outside of user-contrib/ and then copied to /user-contrib/Foundations/Generalities/

Are you sure you did not leave a copy of uuu.vo around somewhere other than in user-contrib/Foundations/Generalities/uuu.vo ?

Also it is important:

a. To have quotes around all file names.

b. To have two layers i.e. Foundations/Generalities/
