Here's an interesting working paper on Warlpiri phonology from the University of Queensland:
 
http://english.uq.edu.au/linguistics/workingpap/ingram/
 
You can see (cf. the "Warlpiri Consonants" link) that the language is typologically close to Dravidian (a long row of oral and nasal stops: bilabial, alveolar, retroflex, palatal [palatoalveolar], velar), no fricatives at all, and a large collection of liquids, including no fewer than three phonemes classifiable as rhotics. This of course doesn't mean that Warlpiri is genetically related to Dravidian -- a typological affinity may result from a combination of pure chance and various implicational universals.

Thanks so much Piotr.  I hate to have put you out looking for
other examples.  There was a question on the IndianCivilization
list as to whether the Indic languages were unique in this aspect.
Off hand it didn't seem likely to me but I wasn't sure and so I
wanted to see what my "guru-ji" had to say :-)
