Hell, what a fu%&ing problem: we use "shtool subst" for adjusting the "configure" script. This internally uses sed(1). Solaris 8's sed(1) has a per-line limit of 4000 characters. Unfortunately ImageMagick's generated "configure" has a line longer than 4000 characters. Hence the sed(1) writes a truncated "configure" script which in turn fails with totally crazy errors (mainly because a closing quote is missing), of course. We fix this by requiring our "sed" package.
