Hi, I have a blast+ packaging that looks to work. Would you mind having a look ? It is in svn at ncbi-blast-plus I tested a sample blastn that worked. I also patched the upstream for a build issue and gcc 4.6 build. Thanks Olivier -- gpg key id: 4096R/326D8438 (pgp.mit.edu) Key fingerprint = 5FB4 6F83 D3B9 5204 6335 D26D 78DC 68DB 326D 8438
