Many same errors on build App from stable ports

[Huajian.Luo]

Hi there,

I found myself stumbling over many failed cases when compile
ports fails while w/ the same kinda error message.

That's each time there was something missing when generating symbol
list, say in /usr/ports/multimedia/ogle-gui
-------
generating symbol list for `libglade-2.0.la'
/usr/bin/nm -B  .libs/glade-init.o .libs/glade-xml.o .libs/glade-parser.o .libs/glade-gtk.o  |  | /usr/bin/sed 's/.* //' | sort |
 uniq > .libs/libglade-2.0.exp
eval: 1: Syntax error: "|" unexpected
gmake[2]: *** [libglade-2.0.la] Error 2
gmake[2]: Leaving directory `/usr/ports/devel/libglade2/work/libglade-2.5.1/glade'
gmake[1]: *** [all-recursive] Error 1
gmake[1]: Leaving directory `/usr/ports/devel/libglade2/work/libglade-2.5.1'
gmake: *** [all] Error 2
*** Error code 2
-------
And I grab the ports from ftp://ftp.freebsd.org/pub/FreeBSD/ports/ports-stable/ports.tar.gz

Thanks in advance for any hints and suggestions.
