Cant find lib file?

I am trying to compile and run bing:
(http://fgouget.free.fr/bing/index-en.shtml, bing_src-1.1.3.tar.gz)
on a sun solaris box. it compiles file but when I try to run it I get the message:

ld.so.1: bing: fatal: libucb.so.1: open failed: No such file or directory
Killed

the "ldd bing" command produces the following:
        libnsl.so.1 =>   /usr/lib/libnsl.so.1
        libsocket.so.1 =>        /usr/lib/libsocket.so.1
        libucb.so.1 =>   (file not found)
        libc.so.1 =>     /usr/lib/libc.so.1
        libdl.so.1 =>    /usr/lib/libdl.so.1
        libmp.so.2 =>    /usr/lib/libmp.so.2
        /usr/platform/SUNW,Ultra-80/lib/libc_psr.so.1

finally, I checked and found the file..:

# find . -name 'libucb.so*'
./usr/ucblib/libucb.so
./usr/ucblib/libucb.so.1
./usr/ucblib/sparcv9/libucb.so
./usr/ucblib/sparcv9/libucb.so.1
#

Anybody have a clue?

Thanks,
Austin.
