Hi Maintainer

Since the upload of src:ga 5.4~beta~r10636+dfsg-4 [1], the build-time 
tests fail to build with errors similar to the following:

bin/bash ./libtool  --tag=F77   --mode=link mpif90   -fdefault-integer-8 
-fno-aggressive-loop-optimizations -g -O2 
-fdebug-prefix-map=/«BUILDDIR»/ga-5.4~beta~r10636+dfsg=. 
-fstack-protector-strong      -L/usr/lib  -Wl,-z,relro -o 
global/testing/big.x global/testing/big.o global/testing/util.o 
global/testing/ffflush.o global/testing/testblas.o  libga.la 
-lscalapack-openmpi -llapack -lblas  -larmci -lm

'blacs_gridexit_'
//usr//lib/libblacs-openmpi.so.1: error adding symbols: DSO missing from 
command line

I was able to work around this with the following:

--- a/debian/rules
+++ b/debian/rules
@@ -9,7 +9,7 @@
  	dh_auto_configure -- 				\
  		--enable-cxx 				\
  		--with-tcgmsg				\
-		--with-scalapack=-lscalapack-openmpi	\

  		--with-blas=-lblas 			\
  		--with-lapack=-llapack			\
  		--with-mpi				\

This might be related to RC bug #854228 in blacs-mpi [2], 'Libraries not 
linked with their deps'.
