Why p11-kit-1 instead of p11-kit?

I added the directory that contains p11-kit-1.pc to PKG_CONFIG_PATH (first
time I've ever had to do this) and was able to get ./configure for
gnutls-2.12.17 to run without errors. However, make then fails with these

make[6]: Entering directory `/home/jim/packages/gnutls-2.12.17/lib/gl'
  CC     c-ctype.lo
  CC     fd-hook.lo
  CC     read-file.lo
  CC     sockets.lo
  CC     asnprintf.lo

  CC     ftello.lo
ftello.c: In function 'rpl_ftello':
ftello.c:45: error: 'fp_' undeclared (first use in this function)
ftello.c:45: error: (Each undeclared identifier is reported only once
ftello.c:45: error: for each function it appears in.)
ftello.c:45: error: '_IOWRT' undeclared (first use in this function)
make[6]: *** [ftello.lo] Error 1

This is on CentOS 6.0 using gcc 4.4.4 on x86_64.

This system has previously had gnutls 2.8.5 installed via yum. Did anything
happen between 2.8.5 and 2.12.17 that I need to account for?

Ahh, actually I now notice that since 2.8.5 there is the option to use
libnettle instead of libgcrypt. It's quite likely that I should built
against libgcrypt. Are there other things like this that I need to be aware

To recap, I need to add support PKCS11 to an existing application that has
to date been built against gnutls 2.8.5. I'd like to figure out the
simplest upgrade path with gnutls to obtain PKCS11 support.
