Bazinga is on a distinguished road

I am following this page for the installation (running ubuntu 16.04):

I wanted to test the beamInCrossFlow tutorial. Everything works smoothly as far as I can tell until Allwmake tries "wmake libso setInletVelocity". Here I get the error message

SOURCE=setInletVelocity.C ;  g++ -m64 -Dlinux64 -DWM_DP -Wall -Wextra -Wno-unused-parameter -Wold-style-cast -Wnon-virtual-dtor -O3  -DNoRepository -ftemplate-depth-200 -I../../../../src/fluidSolidInteraction/lnInclude     -I/opt/foam/foam-extend-4.0/src/finiteVolume/lnInclude     -I/opt/foam/foam-extend-4.0/src/finiteArea/lnInclude     -I/opt/foam/foam-extend-4.0/src/meshTools/lnInclude     -I/opt/foam/foam-extend-4.0/src/dynamicMesh/dynamicFvMesh/lnInclude     -I/opt/foam/foam-extend-4.0/src/lagrangian/basic/lnInclude -IlnInclude -I. -I/opt/foam/foam-extend-4.0/src/foam/lnInclude -I/opt/foam/foam-extend-4.0/src/OSspecific/POSIX/lnInclude   -fPIC -c $SOURCE -o Make/linux64GccDPOpt/setInletVelocity.o
/usr/bin/ld: cannot open output file /opt/foam/foam-extend-4.0/lib/linux64GccDPOpt/ Permission denied
collect2: error: ld returned 1 exit status
The log of the solver fsiFoam then also shows that the library was not successfully loaded.

Reference point coordinates: (0.45 0.15 -0.15)
--> FOAM Warning :
    From function dlLibraryTable::open(const fileName& functionLibName)
    in file db/dlLibraryTable/dlLibraryTable.C at line 124
    could not load cannot open shared object file: No such file or directory

Unknown function type setInletVelocity

Valid functions are :

Tried the HronTurekFsi3 too and similar problem with loading a library.
Not quite sure how I have to deal with the challenge of loading the library correctly.
