[Ifeffit] Ifeffit/iXAFS won't launch in OS 10.6 (Snow Leopard)

[Paul Fons]

The problem with iXAFS is that it is attempting to run a 32 bit  
version of perl contained within the application in a 64 bit process.   
The new version of perl that ships with Snow Leopard is 5.10.0.   I  
pasted the error message from the ixafs shell below.  The solution  
would seem to be to repackage the perl libraries in 5.10.0 and use 64  
bit binaries for the Intel compiler.  I have the Intel compiler as  
well so if you need help, please drop me a line.  Note Perl 5.8 is  
included with Snow Leopard as well and can be invoked by changing the  
defaults of the system, but this is probably a bad thing to do as it  
will change the perl application for all programs and will undoubtably  
cause more problems in the long run than it will solve.


	Cheers,

			Paul
