Bus Errors with Perl/Tk

[David Blank-Edelman]

Hi-

I haven't seen any mention of this in the archives, so I'm wondering  
if anyone else has seen this problem. I'm trying to run another  
package from MacPorts called "cssh" which is essentially a Perl/Tk  
script. I've done every permutation of install/uninstall/clean I can  
think of for perl5.8, tcl/tk8.5 and p5-tk but I still get a situation  
where every Perl/Tk script (even as simple as just "use Tk;") bites  
the dust with this backtrace:

rogram received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_PROTECTION_FAILURE at address: 0x00000000
0x003f550f in boot_Tk__Event ()

#16 0x0000847e in S_parse_body ()
#17 0x00009c66 in perl_parse ()
#18 0x0000197f in main ()

I have a sneaking suspicion that this may either be:
   1) due to a mismatch between p5-tk which describes itself as being  
version  804.027 and Tk which is 8.5.0.
   2) related to the Tk 8.5 upgrade problem (http://trac.macports.org/projects/macports/ticket/13678 
) which also bit me
   3) be a conflict with something that ships with Leopard

p5-tk doesn't appear to have a maintainer so I have to throw myself on  
the mercy of the mailing list. Does anybody have any suggestions on  
how to fix or at least start tracking down the problem? Thanks for any  
help you can offer.
