I run Debian Etch and now I try to compile KDE4, but first i have to compile a Qt version >= 4.3.

When I try to run the configure script I receive the error message in the title. 'make' is installed, it works from bash and sh and 'which' finds it.
Also g++ and a lot of development libraries are installed (the error message is about make anyway).

From my .bashrc file the only uncommented lines are:
Qt Code: 
  1. test -s ~/.alias && . ~/.alias || true 
  2.  
  3. PATH=/space/kde4/qt4-compiled:$PATH 
  4. export PATH 
  5. MAKE=/usr/bin/make:$MAKE 
  6. export MAKE 
  7.  
  8. # This line was appended by KDE 
  9. # Make sure our customised gtkrc file is loaded. 
  10. export GTK2_RC_FILES=$HOME/.gtkrc-2.0

Another issue is that the script does not run unless called as 'sh ./configure', if I run it from bash simply '.configure' it says:

Qt Code: 
  1. bash: ./configure: /bin/sh: bad interpreter: Permission denied
