cross compile opencv via LTIB for ARM

hello everyone,
finally after 1 month now i am reaching my target for cross compile opencv
via LTIB but following are the net connection issue cant get it...

Processing: opencv
====================
Build path taken because: no prebuilt rpm,
Testing network connectivity
OK GPP:

Try opencv-1.1.0.tar.gz.md5 from the GPP
http://bitshrine.org/gpp/opencv-1.1.0.tar.gz.md5:

Can't get: opencv-1.1.0.tar.gz at ./ltib line 802.

These packages failed to build:
opencv

Build Failed

anyone know how to fix it?

What I do is download opencv-1.1.0.tar.gz from somewhere else on the
internet, drop it into the folder where all your other sources are and
presto.

Don't know about the md5 sum ... I never worried about them.

ok..i will try from other website but i want also change in

/ltib/dist/lfs-5.1/opencv/opencv.spec file for URL path....

while i burn the rootfs into board maximum commands are not working like
ls,mkdir,mount etc do u know what is the issue?
