[CentOS] error while loading shared libraries: liblinc.so.1

When trying to run giFTui, I get the following error:

giftui: error while loading shared libraries: liblinc.so.1: cannot open 
shared object file: No such file or directory

So I looked on the web for liblinc.so.1, and learned (?) that it was a 
part of at-spi. Trying to isntall the RPM told me that at-spi was 
already installed. I also tried a YUM install, and it simply said 
"nothing to do".

Which part am I doing wrong? Is there a different RPM I should be 
downloading? Is the problem not a matter of downloading RPMs? What do I 
do to get this "shared object file" on my computer?
