I ran into this when I tried to install BI Publisher on Linux, I solved it by installing libXp (yum install libXp).
Also, extracting the downloaded tar file with WinRAR is not the way to go. Somehow my jar files ended up as directories which resulted in the following error:
Error loading library: generalQueries
Using tar to untar was the way to go here.
