[EMBOSS] error when using the emboss

[mqding]

Dear software user:

I
 have installed the EMBOSS 6.3.1 suit on to my ubuntu system, but when i
 run any software it gives an error information like: "wossname: error 
while loading shared libraries: libezlib.so.1: cannot open shared object
 file: No such file or directory" Do you know how I can solve this 
problems? Thanks very much!

There is no error during the installation process. I simplely type the ./
configure -> make-> sudo make install.
