Hi chichita
... bad address 'distro.ibiblio.org' ...
That's not a valid Tinycore repo address, this is:
http://distro.ibiblio.org/tinycorelinux/
Check your /opt/tcemirror file and correct it if necessary.
You also don't mention whether you are running TC10 or TC11. Whether you are running 32 or 64 bit.
If you are running TC10, you can use tce-load.
If you are running TC11 and want to try the TC10 extension, then:
for 32 bit
http://tinycorelinux.net/10.x/x86/tcz/ncurses.tcz
for 64 bit
http://tinycorelinux.net/10.x/x86_64/tcz/ncurses.tcz
