Around line 2970:

        sotype=none;                                                    \
        elif [ "X${MKPIC}" != "Xno" -a "X${NOPIC}" = "X" ]; then        \

This causes:

/bin/sh: 1: Syntax error: "elif" unexpected

(On that note, I wonder why my SH?=            /bin/ksh is not working
here.)

That "elif" above should probably be "if".

It appears this was done in the  1.1310 to 1.1311 revision.
