New issue 32 by lo...@astron.nl: Environment variable delimited by ${} are
not properly expanded
http://code.google.com/p/casacore/issues/detail?id=32

What steps will reproduce the problem?
1. create a file $HOME/.casarc containing ${} as part of some paths.
For example:
measures.DE200.directory: ${CASACORE_SW_DIR}/data/ephemerides
measures.DE405.directory: ${CASACORE_SW_DIR}/data/ephemerides
measures.line.directory: ${CASACORE_SW_DIR}/data/ephemerides
measures.sources.directory: ${CASACORE_SW_DIR}/data/ephemerides
measures.comet.directory: ${CASACORE_SW_DIR}/data/ephemerides
measures.ierseop97.directory: ${CASACORE_SW_DIR}/data/geodetic
measures.ierspredict.directory: ${CASACORE_SW_DIR}/data/geodetic
measures.tai_utc.directory: ${CASACORE_SW_DIR}/data/geodetic
measures.igrf.directory: ${CASACORE_SW_DIR}/data/geodetic
measures.observatory.directory: ${CASACORE_SW_DIR}/data/geodetic
2. Set environment variable CASACORE_SW_DIR to the parent directory of the
casacore data directory
3. Run a program that uses any of the ephemerides or geodetic tables.
For example:
#include <measures/Measures/MeasTable.h>
#include <measures/Measures/MPosition.h>
#include <iostream>
int main()
{
casa::MPosition mpos;
casa::MeasTable::Observatory(mpos, "DWL");
std::cout << "DWL " << mpos << std::endl;
return 0;
}

What is the expected output?
DWL Position: [15.0164, 1.68353, 19.9167]

What do you see instead?

What version of the product are you using? On what operating system?
Casacore 1.2

Please provide any additional information below.
Removing the {} from the environment variable(s) in the casarc-file
resolves the problem.
