I am new to linux and try to follow the instructions form the boost getting started page.
I am using ubuntu.

When decompressing boost_1_46_1.tar.bz2 I encountered the following errors:
bzip2: compressed file ends unexpectedly;
perhaps it is corrupted.*Possible* reason follow.
bzip2:  Inappropriate ioctl for device
Input file = (stdin), output file = (stdout)

Shouldi be worried ?
