Unable to load required native library 'gwt-ll' error when runnig example under Linux (solution included)

[PeterPal]

Hello,

I've encountered problems running a gwt example under linux. I use
gwt-linux-1.4.60 which I installed by untarring gwt-
linux-1.4.60.tar.bz2 as root in /usr/local. When I run the <example>-
shell shell script as normal user I get the following error:

[ERROR] The browser widget class could not be instantiated
java.lang.UnsatisfiedLinkError: Unable to load required native library
'gwt-ll'. Detailed error:
/usr/local/gwt-linux-1.4.60/libgwt-ll.so: Can't load IA 32-bit .so on
a IA 32-bit platform)

All goes fine when I launch the GWT shell as the root user.

That I installed the tar file as root triggered my grief. As it turns
out, the permissions in the gwt-linux-1.4.60.tar.bz2 archive are a
bit of a mess: files aren't world readable, directory aren't world
traversable and shared libraries are not world executable.

After executing the commands

find . -type f ! -perm -ugo=r -exec chmod ugo+r {} \;
find . -name '*.so' -exec chmod 755 {} \;
find . -type d -exec chmod 755 {} \;

in /usr/local/gwt-linux-1.4.60/ all is fine: I can run my example as
an ordinary user.

I guess the distribution tar file should be fixed.
