Hi, I did succeed in making BioMart run on a 64 bit machine, but it was quite a struggle, taking several days. The heart of the problem was mod_perl, which just plain doesn't like 64 bits. The compilation always breaks. Doing a bit of googling, I discovered that a lot of other people have encountered this, but as far as I can tell, nobody has come up with a solution.
Luckily, the machine I was working on is also backward compatible to 32 bit binaries. So I recompiled everything to be 32 bit. I had to install my own perl, because the system-wide one was 64 bit. Ditto for Mysql, which is needed to compile the database driver. I created a dummy MySQL, with only the libraries and include files in it. Some 64 bit machines don't have any 32 bit compatability, I guess if you have one of those then you may not be able to install BioMart at all. Cheers, David.
