ncbi-blast+-debuginfo-2.2.29-1 lacks sources. Quickly looking at the build log it seems that there are at least two issues that could contribute to this: first, something apparently eats -g* from our C*FLAGS, and second, the build log contains multiple "strip" statements.
Thanks for this, it's really good catch. I will check it in some free moment.
Will be fixed in this build: http://koji.fedoraproject.org/koji/taskinfo?taskID=6462552
