Thanks.

I added this to your packages.

Looks like there's a pre-existing historical error here and lv2-docs 
isn't listed (so when we actually generate the documentation, it ends up 
in the main lv2 package, which isn't really what's wanted).

Keeping the comment these are implibs for modules, so installing them is 
useless would be good.

I think that 'libsamplerate-devel' also needs to be here.
