Because you're building from sources, you'll need to build that library.
I assume you're on a Unix or Linux -- download the Unix sources
and run 

  ./configure
  make 

in your plt tree.  That will build all libraries, as well as 
MzScheme and MrEd.  SrPersist should compile then.

It's because the Microsoft Data Access Components headers have 
that include file.  For better or worse, ODBC is an MS standard.

That file contains Unicode definitions of ODBC procedures, as well as  

  #define SQL_WCHAR         (-8)
  #define SQL_WVARCHAR      (-9)
  #define SQL_WLONGVARCHAR  (-10)

Try commenting out the include.  You might need the definitions 
above, in which case insert them somewhere suitable, such as 
srpersist.h.
