Fatal error when attempting to execute bear.ex from the EuGtk package

I have downloaded and installed EuGtk 4.15.2 and was attempting to run bear.ex and encountered a number of problems. I solved some of them with changes to the EuGtk code but one is a show stopper and I would appreciate some help with this matter.
The first error I encountered was 'ifconfig' not being found. It was installed on my Debian testing/bullseye system but Debian (and maybe other Linux distributions) place it in /sbin and this is not in the path for a normal user. However you can run it if you prefix it with the path, so I changed GtkEngine.e, line 356, to
system(sprintf("/sbin/ifconfig > %s",{ipfile}))
The second error I encountered was that PANGO_WEIGHT_NORMAL considered to be not defined in GtkFontSelector.e. I looked at the code at line 177 and noted that GtkEnums.e has a namespace declaration so I prefixed PANGO_WEIGHT_NORMAL with this and the problem went away. Hence I changed GtkFontSelector.e, line 177, toweight = enums:PANGO_WEIGHT_NORMAL,The third error I encountered was with the libwebkit2gtk shared object file. As I am running testing Debian, my shared object version for this file is more recent than the code is testing for, so I changed GtkWebKit.plugin, line 30, to
dir("/usr/lib/x86_64-linux-gnu/libwebkit2gtk-4*") &
However, after these changes, I still cannot get bear.ex to run. When I run it, the following is printed on the terminal window:
/opt/languages/euphoria/gtk/current/GtkEngine.e:1569 in function deallocate_string_pointer_array()

My kernel is 5.2.9, gtk version is 3.24.10 and gcc version is 9.2.1. I do have the ex.err file but as it was so large I did not want to include it here and did not know how to provide it to the forum.
I note that signal 11 is a SEGV. My eu.cfg file has the paths set correctly so I do not know how to progress this matter further. Any help would be much appreciated.
