You were right. it didn't work. Produced a slightly different error message. I made the changes you recommended for 't2p' to 't2p' and it moved things along. The next error seems to pop up in making 3dDeconvolve_f. The error message is:

In file included from matrix_f.c:304:
mri_image.h:69: error: parse error before "__complex__"

make: *** [3dDeconvolve_f] Error 1
