this probably is the clue :  Hmisc.so expects an libR.so
which is what you get when you do ......./configure --enable-shared
and make for building R itself.

It looks like your version of R-devel
hasn't successfully been built with the ..shared option.
But when using it to build packages, it *does* assume the
'shared R' (libR.so in unix) to be available.

[or Hmisc.so itself or its underlying *.o files were built with 
 a non-shared (i.e. default) version of R ?]

If it the former (and incomplete shared installation) I'd
consider wiping that out and rebuild R afresh -- shared or not --
test R ("make check" or even "make check-all") and when
successful, rebuild Hmisc {removing at least  Hmisc/src/*o
beforehand!} with that version of R.
