The Fedora package smc-fonts has a set of Malayalam fonts (AnjaliOldLipi, Kalyani, Meera, Rachana, RaghuMalayalamSans and Suruma) maintained by SMC. We used to package all these fonts as a single zip file hosted at https://savannah.nongnu.org/projects/smc. These fonts were last updated in 2014 for Fedora, leaving them at version 6.1.
