I must say, Sun employees have been most helpful at solving Sun-related problems I've posted on the internet over the years. (Although this issue arose when I was trying to build Sage on the T5240 Sun at the University of Washington, I have a few Suns at home in England). I like the machines and the OS. Casper Dik, who you may know of, has solved numerous issues for me. Casper is very helpful on comp.unix.solaris. >> The offer is still there for a sqlite developer to fix this properly on >> a Sun, but as a hack, just removing the library works.

Microsoft are paying for a port to Windows, and Sun have contributed towards getting it running on Solaris. You are probably right this sqlite issue is a libtool bug. I've suspected that for some time, as a Google on error messages with 'undefined reference to somefunct...@sunw_x' have appeared in many programs over the years. Apache in particular seems to have suffered it, going back to at least as early as 2005. I had noticed that in most or all of the cases, libtool was used. But I was never sure if it was a libtool bug, or developers using libtool in an incorrect way. I would add, both sqlite 3.5.3 and sqlite 3.6.14.2 build OK on Solaris 10 update 4 with gcc 4.3.2. So I did wonder if it was a bug in gcc 4.4.0 As with many of these software issues, it is often difficult to know exactly where the fault lies. But at least in this case, a simple hack solves the problem for Sage. As a matter of interest, do you know in what release of Solaris the functionality of libpthread was moved into libc? (Don't spend too much time over it if you don't know - it's not that important to me).
