[ECOS] ecos-2.0, configtool and libpng

[John Carter <john dot carter at tait dot co dot nz>]

We are using Mandrake 9.1 and have just d/loaded ecos-2.0 and have found
to our sorrow that configtool doesn't work.

The problem is the version of libpng. Here is the output of 
"ldd configtool"...

ldd configtool
        libgtk-1.2.so.0 => /usr/lib/libgtk-1.2.so.0 (0x40025000)
        libgdk-1.2.so.0 => /usr/lib/libgdk-1.2.so.0 (0x40171000)
        libgmodule-1.2.so.0 => /usr/lib/libgmodule-1.2.so.0 (0x401aa000)
        libgthread-1.2.so.0 => /usr/lib/libgthread-1.2.so.0 (0x401ae000)
        libglib-1.2.so.0 => /usr/lib/libglib-1.2.so.0 (0x401b1000)
        libpthread.so.0 => /lib/i686/libpthread.so.0 (0x401d9000)
        libdl.so.2 => /lib/libdl.so.2 (0x40229000)
        libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x4022c000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40234000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40243000)
        libpng.so.2 => not found
        libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x40322000)
        libtiff.so.3 => /usr/lib/libtiff.so.3 (0x40343000)
        libm.so.6 => /lib/i686/libm.so.6 (0x40388000)
        libc.so.6 => /lib/i686/libc.so.6 (0x403aa000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
        libz.so.1 => /lib/libz.so.1 (0x404de000)

Compare that with the output of ldd for ecos-2.0b1 configtool
ldd configtool
        libgtk-1.2.so.0 => /usr/lib/libgtk-1.2.so.0 (0x40025000)
        libgdk-1.2.so.0 => /usr/lib/libgdk-1.2.so.0 (0x40171000)
        libgmodule-1.2.so.0 => /usr/lib/libgmodule-1.2.so.0 (0x401aa000)
        libgthread-1.2.so.0 => /usr/lib/libgthread-1.2.so.0 (0x401ae000)
        libglib-1.2.so.0 => /usr/lib/libglib-1.2.so.0 (0x401b1000)
        libpthread.so.0 => /lib/i686/libpthread.so.0 (0x401d9000)
        libdl.so.2 => /lib/libdl.so.2 (0x40229000)
        libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x4022c000)
        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40234000)
        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x40243000)
        libm.so.6 => /lib/i686/libm.so.6 (0x40322000)
        libc.so.6 => /lib/i686/libc.so.6 (0x40344000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Mandrake 9.1 only supplies...
locate lib/libpng
/usr/lib/libpng.so.3
/usr/lib/libpng.so.3.1.2.5
/usr/lib/libpng12.so.0
/usr/lib/libpng12.so.0.1.2.5
/usr/lib/libpng.so
/usr/lib/libpng12.so

What suggestions?
