Yes, you're right, wihen installing wxbase, it created the following symlink :
/usr/bin/wx-config ---> /usr/bin/wxbase*****
(From memory as I removed the RPM I built with wxbase, easier to clean my Msk box, and needed to reinstall --force wxGTK.
So two solutions (Mandatory) :
1 - install first wxbase, THEN wxGTK
2 - Manually change the symlink
In Makefile of wxbase :
[code:1]
preinstall
<......>
$(INSTALL_SCRIPT) $(top_builddir)/wxbase-2.4-config $(bindir)/wxbase-2.4-config
cd $(bindir) && rm -f wx-config && $(LN_S) wxbase-2.4-config wx-config
[/code:1]
and there is the exact same one in Makefile from wxGtk
So it creates the symlink, replacing any preexisting
