I am trying to install bowtie2-2.0.0-beta5 on Power 7 linux
I  downloaded the file here:
> http://sourceforge.net/projects/bowtie-bio/files/bowtie2/2.0.0-beta5/
There are three download versions. I downloaded bowtie2-2.0.0-beta5.zip,
because I think the other two versions are for linux-x86_64 and linux-i386.

I extracted the downloaded file. Then I type "make", however, I got error.
Does Bowtie2 support power 7 architecture?
