mpegtoppm is a program built in directory mpegtoppm_dir/. The error occured at the very end of the make when the script tries to move all the results into one directory. You can force the script to finish by using the command 'make -i', which tells make to ignore errors as much as possible and proceed. Of course, you won't get the mpegtoppm program, but unless you want to load MPEG files into AFNI, you don't really need it.

Compilation of mpegtoppm failed with the following error messages:

/tmp/ccpPScFr.s: Assembler messages:
/tmp/ccpPScFr.s:34: Error: suffix or operands invalid for `pop'
/tmp/ccpPScFr.s:37: Error: suffix or operands invalid for `push'
/tmp/ccpPScFr.s:40: Error: suffix or operands invalid for `pop'

These look like compiler problems to me -- like the compiler is generating incorrect code that the assembler hates. Not much we can do about that.
