Hi Dan,

A couple of immediate issues:

1) make fails when it can't find help2man. it then complains (twice)
file2jack isn't found either (an ls after the fact shows it is):

cc  -Os -g -Wall -Wextra -pipe   -std=c99 -D_REENTRANT -ljack
-lpthread -lrt -lsndfile   -lm -lpthread -lrt csrc/jacktransportloop.c
-o jacktransportloop
mkdir man
help2man -N -o man/file2jack.1 /home/sirrom/SRC/jack-file/file2jack ||
{ file2jack --help || :; file2jack --version || :; false; }
/bin/sh: help2man: command not found
/bin/sh: file2jack: command not found
/bin/sh: file2jack: command not found
make: *** [man/file2jack.1] Error 1

2) floating point exception when command issued without options:
Core was generated by `./file2jack'.
Program terminated with signal 8, Arithmetic exception.
#0  compute_frames (argc=<value optimized out>, argv=<value optimized
out>) at csrc/file2jack.c:659
659	    jbuf_len = ((jbuf_len - 1) / denom + 1) * denom;
