gtk20 eval: 1: Syntax error: "|" unexpected

[greg at 7505.com]

command: cd /usr/ports/x11-toolkits/gtk20 && make clean install

FreeBSD 5.3 release, libtool-1.5.10 and attempting to build gtk20
(gtk+-2.4.14) with a fresh cvsup as of Tue Dec 21 11:15 results in the
syntax error shown below.

I have deinstalled & reinstalled libtool as suggested by a previous poster
who was experiencing the same problem, but this did not help.

Any help is appreciated.
