I checked this on my Mac OS X 10.5 machine and it is a problem with  
the libtool script. This causes some of the symbols in the ../tds/ 
tds_objects.a library, which includes the md4.o and therefore the  
MD4Final symbol, not to be present in the final symbol table.

When the iODBC driver manager then loads the libtdsodbc.so driver  
using dlopen (...., DYLD_NOW) the loader tries to fixup all the  
internal symbols and fails to find it.

I tried both the default supplied libtool from the freetds package as  
well as after running:

        glibtoolize -f -c
        aclocal
        autoconf
        automake
        ./configure ....

both both gave similar problems.

I have not yet checked exactly which flag is incorrect in the libtool  
commands for Darwin, but i use a modified one i made myself for 10.4  
which works just fine.

I will do some more checking and will file some bug reports to Apple  
on this subject.

If you want either a binary build of FreeTDS for Mac, or the modified  
libtool script, please contact me directly on iodbc AT openlinksw.com.
