Empty junction.bed TopHat

[vinay052003]

I ran TopHat on Gm12878 cell line RNA-Seq data (fastq files) from ENCODE project. The run was successful (no errors) but my junction.bed and insertion/deletion bed files are empty.
My log/long_spanning_reads.log reports an error:

dyld: lazy symbol binding failed: Symbol not found: __ZNSt8__detail15_List_node_base7_M_hookEPS0_
Referenced from: /Users/vmittal3/usr/local/bin/long_spanning_reads

Is this the reason I didn't get anything in output bed files? If so any suggestions for the solution please?
I am using TopHat version 1.3.3 on Mac OSx 10.6.
Thanks.
