So the first error was:
gtk/Graphics/UI/Gtk/Abstract/Paned.chs.pp:202: error: missing expression between '(' and ')'
gtk/Graphics/UI/Gtk/Abstract/Paned.chs.pp line 202 is:
#if GTK_CHECK_VERSION(2,4,0)
So it looks like that macro is not getting defined properly. It should be defined in gtk2hs-config.h which gets included when pre-processing. What command was it exactly that gave all those errors? Was it ghc -M or cpp or c2hs?
Try these commands and attach the log of what happens, including what commands make runs and any error messages.
touch gtk/Graphics/UI/Gtk/Abstract/Paned.chs.pp
make gtk/Graphics/UI/Gtk/Abstract/Paned.hs
