(I tried to submit this last night and apparently it didn't work; sorry if this is a duplicate) I'm trying to upgrade webkitgtk+ from 1.1.4 to 1.1.7 on two machines, both running linux, but one using gcc 4.4.0 and the other 4.3.3. The build dies on both with the same error message: /usr/bin/mkdir -p ./.deps/DerivedSources ./doltlibtool --tag=CXX --mode=compile /usr/bin/g++ -DHAVE_CONFIG_H -I. -DWTF_USE_ICU_UNICODE=1
