I still think that it is likely that some other install of wxPython is 
being incorrectly imported. If you have an older wxPython build, or perhaps 
one from anaconda, then it's possible that they may be linking to the older 
libpng. Try running these commands to do a new trial in a new clean 
environment.


$ mkdir test  # use whatever test folder location that you want
$ cd test
$ python2.7 -m virtualenv wxvenv # install virtualenv if you don't already 
have it
$ source wxvenv/bin/activate
$ which python # verify it is the one in wxenv/bin
$ which pip    # verify it is the one in wxenv/bin
$ echo $VIRTUAL_ENV
$ echo $PYTHONPATH
$ echo $PYTHONHOME
$ pip install -U -f 
https://extras.wxpython.org/wxPython4/extras/linux/gtk3/fedora-28 wxPython
$ python -c "import sys; print sys.prefix"
$ python -c "import sys, pprint; pprint.pprint(sys.path)"
$ python -c "import wx; print wx; print wx.version()"


If that still gives you the libpng12 error then copy the whole session (the 
commands and all their output) and paste it in a reply to this message.
