This is definitely a mixup of perls.I guess you have compiled
Bio-SamTools for your system's perl (which is threaded), but try to
run in on the perl in /usr/local (which is apparently unthreaded. That
doesn't work. The easiest fix may be to change «#!
/usr/local/bin/perl» in your script to «/usr/bin/perl».
