Hi Tom,

Thanks for the reply. This will work for me, but it seems some cmake
magic is missing from the build procedure because GR_CTRLPORT is not
defined in the config.h that I have. Here are the contents:

#ifndef GNURADIO_CONFIG_H
#define GNURADIO_CONFIG_H
#ifndef TRY_SHM_VMCIRCBUF
#define TRY_SHM_VMCIRCBUF
#endif
#ifndef GR_PERFORMANCE_COUNTERS
/* #undef GR_PERFORMANCE_COUNTERS */
#endif
#ifndef GR_CTRLPORT
/* #undef GR_CTRLPORT */
#endif
#ifndef ENABLE_GR_LOG
#define ENABLE_GR_LOG
#endif
#ifndef HAVE_LOG4CPP
#define HAVE_LOG4CPP
#endif

#endif /* GNURADIO_CONFIG_H */


The cmake step says gr-ctrlport is enabled.
