Seems to me the CCP4 change is exactly in line with the developers'
response to wgscott's bug report at:
https://bugs.launchpad.net/ubuntu/+source/blt/+bug/19148
You have to have the BLT package, whether you shell bltwish or wish.
Modern BLT package doesn't contain bltwish, because
"not a bug. It doesn't make sense to provide a separate shell for each Tcl
Extension. . . .
just use wish for your scripts:
#!/usr/bin/wish
package require BLT
[...] "

In previous CCP4 releases CCP4/ccp4i/bin/loggraph used "bltwish"
exec $CCP4I_TCLTK/bltwish "$0" -- ${1+"$@"}
In 6.2.0 this has mutated to
exec $CCP4I_TCLTK/wish "$0" -- ${1+"$@"}
which doesn't work on our systems, see error below
I've fixed it by changing back to the previous exec bltwish, but does this new
version work for other people? Should it work for me, and with what version of
TCL?
(I look forward to replacing loggraph!)
