Pull in all needed depndencies
# pkg install kdevelop gmake cmake git

Get KDevelop sources
# git clone git://anongit.kde.org/kdevelop.git

# Build the test executable
# mkdir kdevelop/build
# cd kdevelop/build
# cmake ..
# gmake -j4 test_qthelpplugin

Run the test executable and see that it hangs
# ./plugins/qthelp/tests/test_qthelpplugin testDefaultValue
