My standard approach is the go in the library directory for the compiler and do an "nm" which preints out the symbols in the libraries and then grep for the one I want.

I'm not familiar with Sun's nm output, but it looks like some variation of your missing function is defined in on of the above.  I don't see a signature that matches __vlog__ exactly.  Sometimes there is an underscore mismatch that the linker handles internally (at least on windows with gcc that appears to be the case). You might try adding -mvec to the command and see if that solves the problem, but I'll bet there is an underscore issue here.

see ya,
