How do you import Block Chain from bitcoincharts?
If you are using the not-yet-released Bitcoin.org client v0.7, you can use the -loadblock=FILE to import the blockchain from the blk0001.dat file. [Update: actually need to do two of those inline, -loadblock=blk0001.dat -loadblock=blk0002.dat in order to get both to load.]

There is a blockchain with index through block 170,000 here:


http://sourceforge.net/projects/bitcoin/files/Bitcoin/blockchain/


That is the most complete distribution of the blockchain that I know of where the blkindex.dat is included.
