dependant mono sthn libc 2.1.1.

Ena swsto sxhma dependency control 8a eprepe na exei poly pio fine
granularity, se epipedo arxeiou isws. Kaneis link me thn "libpapari.so.2.1"?
Eisai dependent apo thn "libpapari.so.2.1", eite ayth brisketai sto
"papari-dev" package eite sto "elefantas" package.

Blepw to ports collection toy FreeBSD, me ena flexibility poy den eida pote
