@sgemv: WRAPIT error from linking to LAPACK

 Hi folks,

I am trying to wrap a f90 subroutine that calls lapack library.
The WRAPIT part compiles very well, but when I run the ncl script, I got the
error:

> ncl
 Copyright (C) 1995-2004 - All Rights Reserved

ncl 0> external eof "./eof_scalar.so"
warning:An error occurred loading the external file ./eof_scalar.so, file
not loaded
rtld: 0712-001 Symbol @sgemv was referenced
      from module ./eof_scalar.so(), but a runtime definition
      of the symbol was not found.
rtld: 0712-002 fatal error: exiting.
ncl 1>

Here is
1) the link for the f90 subroutine:
http://www.cgd.ucar.edu/cas/software/eof_scalar.html

2) the WRAPPER:
C NCLFORTSTART
  SUBROUTINE eof_scalar( ucM, ucN, ucFd, ucE, ucL_N1, ucC )
  INTEGER ucM,ucN
  REAL ucFd(ucM,ucN),ucE(ucM,ucN),ucL_N1(ucN),ucC(ucN,ucN)
C NCLEND

3) the compile process
> WRAPIT -L /usr/common/usg/LAPACK/3.0 -l lapack -l essl eof_scalar.stub
eof_scalar.f90

WRAPIT Version: 041106
COMPILING eof_scalar.f90
** eof_scalar === End of Compilation 1 ===
1501-510 Compilation successful for file eof_scalar.f90.
LINKING
END WRAPIT

I am running AIX with the compile xlf90
When I try to locate @sgemv, here is what I get:

> grep @sgemv *
eof_scalar.so:NhlPError
eof_scalar.so:?
