nm says nothing for `nm libcblas.a | grep f2c_ctrmv`. btw, blaswrap is
needed only if i build clapack with existing fortran libblas.

Now I'm trying CC (not GCC), then check out sbcl 1.0.38.

I saw it and some time tried to use. But now it is modifying
quickly. :)
LLA uses fortran lapack, and I really need C lapack for checking some
ideas.

f2c_ctrmv exists in static lapack_LINUX.a. Then I convert it into
shared library

ar x lapack_LINUX.a
cc -shared *.o -o libclapack.so
nm libclapack.so | grep f2c_ctrmv # this finds the symbol in
libclapack.so

but (load-shared-object "libclapack.so")
brings 'undefined symbol "f2c_ctrmv"' again.

:(

clisp refuses to open, using ffi:open-foreign-library.
cmucl warns about unresolved symbol, but loads the library with load-
foreign.

it seems not to be a problem of sbcl

Here is another thing to try: make sure libraries are loaded in the
correct order. Load explicitly the blas library first.

(by the way (expt 'good-luck 2) would throw an exception. duh.)
