You shouldn't have a problem as long as you use GNU's version of tar to uncompress the volume, as the Solaris's version does not support long file names.
You can get this from the mysql website. If this is not the problem posting the tailing error messages received when trying to configure the program would provide more help.
I've recently just perform the same installation on a Ultra 10s, and apart from the above problem there were no other concerns.
Hope this help,
