updating to 1.4

[xueyue]

I updated swarm from 1.3.1 to 1.4.1 using
the redhat5.1/5.2 (redhat5.1 in my pc) RPM
distribution. I also updated lib- library. 
But. However, when I compile the 1.4.1 (and 1.3.1) swarmapps according
to Makefile, the following message is displaye
/lib -Wl,--rpath -Wl,/usr/lib -Wl,--rpath -Wl,/usr/lib
/usr/lib/swarm/libtkobjc.so: undefined reference to `png_set_sRGB'
collect2: ld returned 1 exit status
make: *** [hello-world] Error 1

----------------------

I am now trying to find out the reason. But if anyone can point out to
me, it would be grateful.
