Hi Bilal,

welcome to DUNE and PDELab!

Your problem isn't as bad as it seems - the core modules of DUNE and the PDELab library
are both fine, this error is just in an example program in the PDELab Howto. You get it because
you are missing the external grid library UG - see http://www.dune-project.org/external_libraries/install_ug.html
for installation instructions. That said, you can also just ignore the error and start working with PDELab,
or you can switch to a different grid manager by commenting line 114 in poisson_uniform.cc and uncommenting
one of the two following lines.

Just a quick note: If you have questions about PDELab, please use the PDELab mailing list (dune-pdelab at dune-project.org)
instead.

Best,

Steffen
