[xcrysden] 1.5.53 installation

[Martin Kroeker]

The missing functions seem to be from the standard c library - older
versions of the linker used to add that automatically when you compiled
something.
Try editing the line "MATH = -lm" near the top of your Make.sys so that
it reads "MATH = -lc -lm" and then run "make" again. (You may need to
run "make clean" before the "make" so that everything gets rebuilt).

Hope this helps
Martin
