The above is a strange (and serious) error.  It appears to indicate the
the shell couldn't handle the following line in the configure script:

    if { (eval echo configure:1552: \"$doit\") 1>&5; (eval $doit) 2> &5; }; 
then

What shell ran the configure script?  Has it had any patches applied to
it?
