No I haven't but I'll certainly give it a look.

My pdksh is much smaller: $ ls -ld /usr/local/bin/ksh -r-xr-xr-x 1 root wheel 681584 Jan 23 2007 /usr/local/bin/ksh $ pkg_info -W /usr/local/bin/ksh /usr/local/bin/ksh was installed by package pdksh-5.2.14p2_2 It's also statically compiled. I wonder what is bloating yours so much.
