To perform static linking it would be enough to add -static flag to LDFLAGS
in sgroup's Makefile (gcc). But I'm not sure there exists universal cure for problems
like that.
For example, being compiled on a newer Linux (kernel 2.6.21.5), I have got the error

FATAL: kernel too old
Segmentation fault

from an older machine (kernel 2.6.13-15), even not a glibc problem,
i.e., as far as I can see, to keep binary compatibility,
one has to use binaries compiled on an older
machine/software.
