gfortran/BLAS failure Mac 10.6

[Michael D. Godfrey]

Here is what is wrong with Mac 10.6 ./configure:

configure:33009: checking whether LSAME is called correctly from Fortran
configure:33032: gfortran_4.4 -o conftest -O -mieee-fp  conftest.f 
/System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/veclib.framework/Versions/A/libBLAS.dylib 
-lm >&5
Undefined symbols:
  "_lsame_", referenced from:
      _main in ccJlEGZv.o
      _main in ccJlEGZv.o
ld: symbol(s) not found
collect2: ld returned 1 exit status
configure:33032: $? = 1
configure: program exited with status 1
configure: failed program was:
|       program main
|
|       logical lsame,w
|       external lsame
|       character c1,c2
|       c1 = 'A'
|       c2 = 'B'
|       w = lsame(c1,c2)
|       if (w) stop 1
|       w = lsame(c1,c1)
|       if (.not. w) stop 1
|
|       end

Do I need some option to cause undefined symbol to be found?
