OK, got it. The Gmakefile was wrong.
The change is:

cd src.contrib/CERL/misc/m.eigensystem/

diff -r1.5 Gmakefile
12c12
< $(BIN_INTER)/$(PGM): $(OBJ)
---
> $(BIN_CMD)/$(PGM): $(OBJ)

If you are not compiling GRASS yourself, you may try to
copy WITHIN GRASS:

cp $GISBASE/etc/bin/inter/m.eigensystem GISBASE/etc/bin/cmd/m.eigensystem

Then run

 m.eigensystem < inputfile.txt

This should work.
