Hello. I've tried to install xastir on another system, with wget
and it works. difference inbetween systems is mainly used libc
(the non-working system uses uclibc)

previous version (the one without tile cache) was working fine on
uclibc machine.
memory is quite avail, free reports over 1.8G of swap and 91M totally free 
ram (out of 610M physical ram avail)

xastir also fails to exit (it needs to be killed with -9 signal) when
it tries to 'remove' broken tile.

i will try upgrading libpng, so far i've upgraded curl (no help)
and then recompiled it with wget (did not change a thing either).
