[Rd] Lapack calls from fortran

[Paul Gilbert]

I am trying to call the lapack routine dgesv in the R distribution from 
the fortran code for a package, but when I dyn.load("dse1.so") I get an 
error about undefined symbol: dgesv_

I thought the proper incantation was

MAKEFLAG="FLIBS=/path to/R-2.1.1/libRlapack.so" R CMD SHLIB dse1.f

but apparantly not. How does one do this?

Thanks,
Paul
