I had some old glib (in irssi's opinion), so i compiled new one.
Now irssi throws me:
*** 'pkg-config --modversion glib-2.0' returned 2.18.1, but GLIB (2.4.7)
*** was found! If pkg-config was correct, then it is best
*** to remove the old version of GLib. You may also be able to fix the error
*** by modifying your LD_LIBRARY_PATH enviroment variable, or by editing
*** /etc/ld.so.conf. Make sure you have run ldconfig if that is
*** required on your system.
Now, removing old one could cause problem, because some other packets may use it.
How could i avoid this error?
