Failed dependencies: libaspell.so.15 is needed by gaim-0.71-2 libgtkspell.so.0 is needed by gaim-0.71-2
I believe you need to install those RPM's first that would give you those libraries.
Better , you have other system where this is working fine,find out from which those files/libs,ie "libgtkspell.so.0" "libaspell.so.15" came from
Ex:
On my Redhat-8 box, 1)
# whereis libaspell.so.15 libaspell.so: /usr/lib/libaspell.so.10
# rpm -qf /usr/lib/libaspell.so.10 aspell-0.33.7.1-16
<<so u need to install RPM 'aspell-0.33.7.1-16'
