I sincerely find this is more a limitation fo your tools than of our build system, why is jhbuild adding the poppler LD_LIBRARY_PATH when running in poppler? it seems to me if you're running a poppler too it should only add the dependencies of the libraries it needs, not of itself too. Anyway if you can produce a patch that doesn't interfere with my workflow and it helps both you and Adrian i guess we could commit it if noone else disagrees.
