[libvirt] libvirt - Configure fails with error message

Hi, When i try to run configure it fails asking me to install the gnutls library, which is already installed. Output from configure: checking for struct _xmlURI.query_raw... no checking gnutls/gnutls.h usability... yes checking gnutls/gnutls.h presence... yes checking for gnutls/gnutls.h... yes checking for gnutls_handshake in -lgnutls... no configure: error: You must install the GnuTLS library in order to compile and run libvirt [user1@xxx libvirt-0.4.6]# rpm -qa | grep gnutls gnutls-devel-1.4.1-3.el5_1 gnutls-1.4.1-3.el5_1 After some checking in configure.in I verified that what was really missing is libgcrypt-devel. I believe the error message should be updated and provide more details or at least a check for libgcrypt should be done before the gnutls check. Ricardo
