Lingua italiana (babel) su Ubuntu

Salve a tutti, ho un problema durante l’utilizzo di LaTeX su Ubuntu (ver. 8.10),
premetto che uso come compilatore Texmaker.
Ecco il mio problema: mi torvo a scrivere su uno stesso file sia da Windows che da Ubuntu; ora però mentre su Windows, con TexnicCenter non ho problemi né warning; lo stesso file con lo stesso preambolo mi dà un warning sulla lingua:
Riporto qui il warning per intero (per sicurezza)
`

Mi rendo conto che è un po’ lunghetto….
Ho già cercato problemi analoghi sul forum, ma l’unico che ho trovato riguardava alla fine ‘pasticci nell’istallazione di tex-live2008″…non credo sia il mio caso…
Sapreste aiutarmi?
Grazie
Nicola
