This is a compliled versions of Mosaic 2.5 beta 5.
Seems to work fine on Solaris 2.4.  Haven't done
much test but if find something seriously wrong
email palowoda@fiver.sns.com

Untar the archive.
Copy the Mosaic-2.5.solx86/src/Mosaic to your 
local executable directory. Usally /usr/local/bin.

Read any release notes for local X configuration.
