Sorry, guys, for wasting bandwidth on this! You guys gave just the answer I wanted to hear. Sounds like there aren't any problems. Not knowing about such things, I was scared by the following quote. Perhaps binaries do not need to be compiled as 64 bit binaries on a 64 bit machine? Or perhaps it's way out of date (2004) or simply wrong. from http://www.osnews.com/story/5768/Are_64-bit_Binaries_Really_Slower_than_32-bit_Binaries_/page3/ " ... The Compile Factor Getting applications to compile as 64-bit binaries can be tricky. The build process for some applications, such as OpenSSL, have 64-bit specifically in mind, and require nothing fancy. Others, like MySQL and especially PostgreSQL (I was originally going to include PostgreSQL benchmarks) took quite a bit of tweaking. There are compiler flags, linker flags, and you'll likely end up in a position where you need to know your way around a Makefile..."
