This took a little digging. There are no rpms for sunbird in the repo, so this was a workaround
1 - download the linux tarball from mozilla -
http://www.mozilla.org/projects/cale.../download.html
2 - make sure you have the following installed -
libstdc++-4.1.2-12
compat-libstdc++-33-3.2.3-61
3 - unzip the tarball and move it to /usr/local/sunbird (chown.root.root -R sunbird)
4 - in user local bin, I made the following bash script
#vi sunbird
<start>
#!/bin/sh
LD_LIBRARY_PATH=/usr/local/sunbird
/usr/local/sunbird/sunbird
<finish>
#chmod a+x sunbird
and it worked. (the LD_LIBRARY_PATH was to only non-obvious part)
rpm would have been nice - but it's working
