Hi, blast runs out of -rv2 not -rv2.18. As said earlier
<dblast07:113> diff ~/lib/libBlast.so ~/cvs_v2/BlastLib2/libBlast.so

gives no diff. All changes in v2 are checked in and we (or at least I)
always compile out of straight cvs -rv2 check out. Also

<dblast07:113> cat ~/cvs_v2/BlastLib2/CVS/Tag gives
Tv2

Maybe the pid flag is a thing to look at and if so I'll take it out
from blastrc. libBlast has not significantly changed in the past 3
weeks and I've never experienced such a freeze EXCEPT when you are
crunching data and somebody changes/saves lrn.C. Then root may just
abort or freeze. Will look into that.

This was already discussed and put in the minutes of the last software
meeting.

As far as havin a deal with satan him/herself, I'll investigate directly.
