On our EMT64 testing we found that the 32bit versions run slightly faster
than the 64bit versions.

These are runtimes for various algos on  a 3.0GHz EMT64:

Algorithm		32Bit	64bit

Wublastn		34.70	40.34
Wublastp		375.26	219.61
Wutblastn		785.54	713.88
genewise		95.16	113.99
exonerate		550.22	588.17
