GWT - 1.5.3 - Ubuntu - libstdc++.so.5: cannot open shared object file

Started my work successfully on GWT 1.5.3 for a test project of mine.

I followed the sample instructions as given in the GWT website.

After using the projectCreator and applicationCreator scripts - when I tried to import the project in eclipse and run it - I encountered the following error trace.
/opt/software/gwt-linux/mozilla-1.7.12/libxpcom.so:libstdc++.so.5: cannot open shared object file: No such file or directory

I was working on Ubuntu 8.04.

I did the following

 sudo apt-get install libstdc++5

to get rid of the above mentioned error to install the missing .so files.  That fixed the issue.
