Ok, if I comment out the comedi_calibrate and testing references in the top
Makefile of the library tree, all builds and installs. The install of the lib
went to /usr/lib. I run ldconfig then cd back into the comedi_calibrate or
testing dir and do a make again with the same results. Correct me if I'm wrong,
but aren't the .so files for runtime and the .a files for compile/link time?

pc244:/usr/src/Advantech/comedilib-0.7.19 # make install
install -d /usr//include
install -m 644 include/comedilib.h /usr//include
install -m 644 include/comedi.h /usr//include
ln -sf libcomedi.so.0.7.19 /usr/lib//libcomedi.so
install -m 644 lib/libcomedi.a /usr/lib/
install lib/libcomedi.so.0.7.19 /usr/lib/
ln -sf libcomedi.so.0.7.19 /usr/lib//libcomedi.so.0
install -s -m 755 comedi_config/comedi_config /usr/sbin/
#install -s -m 755 comedi_calibrate/comedi_calibrate /usr/bin/

pc244:/usr/src/Advantech/comedilib-0.7.19 # ldconfig
pc244:/usr/src/Advantech/comedilib-0.7.19 # cd comedi_calibrate
pc244:/usr/src/Advantech/comedilib-0.7.19 # make

	same results
