Title: An easy one-- I hope.

Hi!
        I think this should be a fairly easy question but for the life of me I cannot find a solution. I have a Solaris 2.6 system that I have built and installed several versions of libtiff in my attempt to solve my woes. I am using GCC 2.8.1. The builds from source go through without error and I have also tried the binary package for Solaris 2.6 from the Solaris Freeware site. In both cases I am running into problems with unresolved references on sqrt, log, and exp when I attempt to use the library. We have some code which was written using tiff-3.30 and we are attempting a recompile as we are replacing a SPARC 1000 (Solaris 2.4) with an Enterprise 450. It's not complicated code but I am having no end of difficulties. The libtiff code section and a sample of the error messages are below. Oddly enough I have been using several other libraries on the same box (both shared and static) without difficulty. I know this post is rather long but I am hoping this provides complete information. Any assistance would greatly appreciated.

Here is a sample of the errors...
