Duh, of course. That is because there is no incdir variable, so 
"${incdir}" will expand to "\${incdir}". The real variable is called 
includedir. 

This of course brings the question whether ltp expects incdir or 
includedir, and if it is the latter, then your changes so far have not 
made any difference when it comes to includedir, which means they 
shouldn't be needed.
