Yes, you are right, googling .. gaim-1.5 or 1.5.0
gives zero results, so I used my own archive with
old install DVD's ( grep gaim-1.5.0 .. etc. ) to
find that "getslack" containing all old source
code was a place to look.
Today I found that : Google >> "Advanced Search"
can do it too ( keyword .. gaim 1.5.0 source )
and found this quickly
