gaim requires the gnutls package, which isn't shipped with SUSE Linux < 9.1.
I also provide those packages on my site:
  » opencdk (which is required to install gnutls)
  » gnutls
  » libtasn1

Please install those packages first (first opencdk, followed by libtasn1, then gnutls and finally gaim)

Note that for SuSE 9.1 you must install the gnutls package shipped with SuSE !
