You may be suffering from restrictions to the list of symbols being exported 
by libtds.  Try something like this:

$ make clean
$ for T in src/*/Makefile
  do
        sed 's/-export-symbols-regex.*$//' $T \
                | diff -u $T - \
                | patch
  done
$ make; make install

The "sed" command will remove the restriction, causing libtds to export the 
names of the libc (and other) functions it uses.  I'm assuming you have GNU 
diff and patch.  If not, you'll need to edit the Makefiles manually.  

[I would like to see this symbol list optimization removed, or applied only 
to systems whose linker is known (by autoconf) to support it.  I still don't 
understand why we're bothering with export-symbols-regex.]
