Update -
Solved! I finally got Loch to compile. The change is in the Loch Makefile, highlighted below in red. With this final change the entire Therion package will compile.
==================
# PLATFORM LINUX
CXX = c++
CC = gcc
POBJECTS = lxR2P.o
#ifeq ($(VTKV6),1)
#VTKLIBS = -lvtkCommonExecutionModel-$(VTKVERSION) -lvtkCommonDataModel-$(VTKVERSION) -lvtkCommonCore-$(VTKVERSION) -lvtkFiltersCore-$(VTKVERSION) -lvtkFiltersHybrid-$(VTKVERSION) -lvtkIOLegacy-$(VTKVERSION) -lfreetype -lpng -ljpeg
#else
#VTKLIBS = -lvtkHybrid -lvtkImaging -lvtkIO -lvtkGraphics -lvtkFiltering -lvtkCommon -lfreetype
#endif
VTKLIBS = -lvtkCommonExecutionModel -lvtkCommonDataModel -lvtkCommonCore -lvtkFiltersCore -lvtkFiltersHybrid -lvtkIOLegacy -lfreetype -lpng -ljpeg
CXXPFLAGS = -DLXLINUX $(shell wx-config --cxxflags) -Wno-deprecated $(shell freetype-config --cflags) -I$(VTKPATH)
CCPFLAGS = -DLXLINUX $(shell wx-config --cflags)
LXLIBDIR = linux
PLIBS = $(shell wx-config --libs --gl-libs) -L$(VTKLIBPATH) $(VTKLIBS) -lGLU -lGL -lpthread -lX11 -lz
LXPLATFORM = LINUX
