Hi folks:

I've found two potential problems with CCP4 on OS X which, in 
conformity with the current trend in international affairs, want to 
respond to with a pre-emptive first strike.  (However, these problems 
aren't imaginary):


1.  For those running OS 10.2.x, if you updated to tcl tk v. 8.4 via 
fink you may find you get the following error with ccp4i now:

% ccp4i
dyld: /sw/bin/bltwish can't open library: /sw/lib/libtk8.3.dylib  (No 
such file or directory, errno = 2)
Trace/BPT trap


This is because blt makes explicit reference to the older library.  You 
need to recompile it with a command like

% fink rebuilt blt

(This also needs to be done with python by the way,  if you have 
installed it with fink, as the tcltk update broke tkinter.)


2:  If you are just now upgrading to 10.2.x, you will find that blt and 
mozilla, as well as a few other things you may need, are only available 
in the "unstable" tree of fink.

Directions on how to deal with this issue, as well as how to use fink 
to install lots of crystallographic software (ccp4, cns, etc..) using 
fink installation scripts that I made are here:  
http://chemistry.ucsc.edu/~wgscott/xtal/xtalfink_html.html   The 
advantage of this is it takes care of all the dependency headaches 
automatically, and you can type   %fink install ccp4    and then go to 
lunch as it downloads and compiles ccp4 and all its dependencies.

HTH,

Bill Scott
