And dgemm isn't linked in either. And that is a function in sunperf. 
What am I missing? How should I do to link them in? Is there any
flag that I need to add to R SHLIB?
Do I need to do something else before being able to dyn.load-ing the
library? Thank you very much, Giovanni

This is my R SHLIB command:

Fri<15:56>gpetris[298]>R SHLIB tryit.c
cc -I/export/home/share/R/R-1.4.0/lib/R/include -I/export/home/gpetris/C -I/usr/local/include -I/export/home/share/include   -KPIC  -xO5 -dalign -xlic_lib=sunperf -c tryit.c -o tryit.o
cc -G  -o tryit.so tryit.o -L/export/home/gpetris/lib/SUN/32bit -lutil -lrand -L/usr/local/lib -L/export/home/share/lib  
Fri<15:56>gpetris[299]>cat Makevars
