undefined reference to `xmlXPathContextSetCache'

Hello,

Under OpenBSD 3.9, I'm trying to compile libxslt-1.1.17.
I just downloaded the tar.gz file, untared it, and tried the default
configure/make usual way.
I also tried with many sets of options, the maximum longest command line being :
./configure --prefix=/usr/local --without-plugins --without-crypto
--without-python --disable-static --enable-shared

I tried it with so many combinations I can't remember all.

In every cases, here is what I get :

[...]

May you explain me if there's a way to correct that ?
