Thanks for info. I successfully compiled editor using the following Debian Sarge packages:
libwxgtk2.4
libwxgtk2.4-contrib
libwxgtk2.4-contrib-dev.
Only I had to change names of libraries in Makefile.unix to debian compatible:
LIB_WXXRC=wx_gtk2_xrc-2.4
LIB_WXSTC=wx_gtk2_stc-2.4
I changed to:
LIB_WXXRC=wx_gtk_xrc-2.4
LIB_WXSTC=wx_gtk_stc-2.4
