==================================================
LALSuite has now been successfully configured:

* LALFrame library support is $LALFRAME_ENABLE_VAL
* LALMetaIO library support is $LALMETAIO_ENABLE_VAL
* LALSimulation library support is $LALSIMULATION_ENABLE_VAL
* LALBurst library support is $LALBURST_ENABLE_VAL
* LALInspiral library support is $LALINSPIRAL_ENABLE_VAL
* LALInference library support is $LALINFERENCE_ENABLE_VAL
* LALPulsar library support is $LALPULSAR_ENABLE_VAL
* LALApps library support is $LALAPPS_ENABLE_VAL
* Doxygen documentation is $DOXYGEN_ENABLE_VAL

and will be installed under the directory:

${prefix}

Now run 'make' to build LALSuite,
and run 'make install' to install LALSuite.
