-Alternatively, it is relatively straightforward to fix the compilation 
-problems in plib

-The two errors reported are the following:
-ssgaSky.h:107: error: extra qualification ‘ssgaCelestialBodyList::’ on member ‘ssgaCelestialBodyList’
-ssgaSky.h:195: error: extra qualification ‘ssgaCloudLayerList::’ on member ‘ssgaCloudLayerList’
-
-To fix, open the file plib-1.8.4/src/ssgAux/ssgaSky.h
-
-and change line 107 to read:
-  ~ssgaCelestialBodyList () { removeAll(); }
-and change line 195 to read:
-  ~ssgaCloudLayerList () { removeAll(); }
-
-In other words, remove the "extra qualification" parts from both lines. 
-After these changes, plib-1.8.4. should build and install correctly.
