I think the problem is in other part -- the build parameters must be adjusted to set internally the proper path to modules. Explicitly setting the path in config proved to be a bit more dangerous when having more than one installation, but also because there are parts of code relying on those paths, especially for default config path -- if the build system is not setting those defines properly, there can be other side effects in long term.

If one runs:

``` kamailio -I ```

it should print the right path to modules and kamailio tries to load from there. If there is a mismatch from what `kamailio -I` prints and where the modules were installed, then it has to be fixed.

As a side note for the future, prefix the commit message with the component that is affected, in this case being kamailio.cfg, so it should look like:

``` kamailio.cfg: short commit description here ``` I am closing this one and further discussions should be on the issue you opened (#1096).
