Dear Amber community,
 I have been trying to install the leap module of AMBER8 in Linux Suse 10.0 x86_64 version. Basically tleap installs just fine. However, the installation of xleap seems to have a linking problem with ld command giving the following following error message.
 gcc -o xaLeap basics.o sysdepend.o stringExtra.o varArray.o getline.o avl.o pdb_format.o pdb_read.o pdb_sprntf.o pdb_sscanf.o pdb_write.o vector.o zMatrix.o sort.o bag.o hash.o dictionary.o database.o nVector.o ring.o matrix.o fortran.o displayer.o assoc.o atom.o byteArray.o collection.o container.o internal.o list.o loop.o molecule.o oDouble.o oInteger.o oString.o objekt.o parmSet.o residue.o unit.o unitio.o tripos.o graphUtil.o select.o amber.o build.o elements.o library.o chirality.o minimizer.o model.o parmLib.o pdbFile.o tools.o variables.o parser.o help.o helptext.o octree.o commands.o mathop.o block.o restraint.o hybrid.o xTank.o xAction.o x3d.o xBasics.o xaLeapc.o xaUnitEditor.o xaTable.o xaAtomTable.o XrawRegistr.o xaCommand.o xaTools.o xaAtomParmTable.o xaBondParmTable.o xaAngleParmTable.o xaParmEditor.o xaTorsionParmTable.o xaImproperParmTable.o xaHBondParmTable.o ../Xraw/libXaw.a ../Wc/libWcLeap.a ../Xpm/libXpm.a ../Xmu/libXmu.a -L/usr/X11R6/lib -lXt!
 -lSM -lICE -lX11 -lm -lpthread
 /usr/lib64/gcc/x86_64-suse-linux/4.0.2/ld: cannot find -lXt
 collect2: ld returned 1 exit status
 make[1]: *** [xaLeap] Error 1
 make[1]: Leaving directory `/home/jenk/amber8/src/leap/src/leap'
 make: *** [install] Error 2
 Although I set a link by
 ln -s /user/bin/ld /usr/lib64/gcc/x86_64-suse-linux/4.0.2
 I still keep getting the same error message above.
 Does anyone of you know how to troubleshoot the linking problem of xleap in Linux Suse x86_64 ?
