macport wxt problem

[Peter]

Hello,

when I compile gnuplot 4.6 with macport wxt in mac os x 10.6 with xcode_4.2, my macport was self updated to the latest version.

I got the following errors.

In file included from ./plot.h:46,

                 from wxterminal/wxt_gui.h:113,
                 from wxterminal/wxt_gui.cpp:96:
./mouse.h:189: error: variable or field 'set_ruler' declared void
./mouse.h:189: error: '_Bool' was not declared in this scope
./mouse.h:189: error: expected primary-expression before 'int'
./mouse.h:189: error: expected primary-expression before 'int'
./mouse.h:197: error: '_Bool' has not been declared

In file included from wxterminal/wxt_gui.h:113,
                 from wxterminal/wxt_gui.cpp:96:
./plot.h:53: error: '_Bool' does not name a type
./plot.h:54: error: '_Bool' does not name a type
./plot.h:55: error: '_Bool' does not name a type

how to resolve such a problem ?

Thanks.
