Hello,
I'm seeing the following with v3.15-rc2:
$ ~/bin/perf report --gtk
GTK browser requested but could not find libperf-gtk.so
The library file is in $HOME/lib64 and perf attempts to look it up.
However, printing out dlerror() output shows the following:
[penberg@localhost hornet]$ ~/bin/perf report --gtk
/home/penberg/lib64/libperf-gtk.so: undefined symbol: sort_sym
GTK browser requested but could not find libperf-gtk.so
I'm not sure how this is supposed to work. sort_sym() is defined in
the 'perf' executable so how is libperf-gtk.so going to see it?

Hmm.. strange. On my system, it works perfectly..

I'm also not sure.. maybe linker finds the symbol in the executable in
case of dlopen()?
Thanks,
Namhyung
