Segmentation fault when set term wxt in gnuplot

[renzresearch]

Segmentation fault occurs when set terminal to wxt in gnuplot. No message shows until the next session of gnuplot is launched. Please see the attached file. I have tested x11 and aqua terminals. No such error occurs. Two types of messages are:

objc[24047]: Class wxNSAppController is implemented in both /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/libwx_osx_cocoau_core-3.0.0.4.0.dylib (0x109909c40) and /opt/local/Library/Frameworks/wxWidgets.framework/Versions/wxWidgets/3.0/lib/libwx_osx_cocoau_core-3.0.dylib (0x10759ac40). One of the two will be used. Which one is undefined.

and

../src/common/object.cpp(251): assert "classTable->Get(m_className) == NULL" failed in Register(): Class "wxHtmlHelpController" already in RTTI table - have you used IMPLEMENT_DYNAMIC_CLASS() multiple times or linked some object file twice)?

Error message shown after gnuplot is launched if the previous session had a segmentation fault

This is probably a duplicate of #62348.

sudo port -f uninstall wxwidgets-3.0
sudo port -v -s install wxwidgets-3.0

worked for me. gnuplot is working now. Thanks.
