Avoiding the default gsl error handler

The error message before the break is
gsl: qags.c:548: ERROR: cannot reach tolerance because of roundoff error
Default GSL error handler invoked.

Just some more info, before the configuration for installing root were:
“$ALICE_PREFIX/root/$ROOT_SUBDIR/src/configure”
–with-pythia6-uscore=SINGLE
–with-alien-incdir=$GSHELL_ROOT/include
–with-alien-libdir=$GSHELL_ROOT/lib
–with-monalisa-incdir="$GSHELL_ROOT/include"
–with-monalisa-libdir="$GSHELL_ROOT/lib"
–with-xrootd=GSHELL_ROOT \ --enable-minuit2 \ --enable-roofit \ --enable-soversion \ --disable-bonjour \ --disable-rfio \ --disable-castor \ --enable-builtin-ftgl \ --enable-builtin-freetype \ --with-clang \ --with-f77=( which gfortran )
–with-cc=( which clang ) \ --with-cxx=( which clang++ )
–with-ld=$( which clang++ )
–disable-fink
–enable-cocoa
–prefix="$ROOTSYS"
–incdir="$ROOTSYS/include"
–libdir="$ROOTSYS/lib"
–datadir="$ROOTSYS"
–etcdir="$ROOTSYS/etc"

Now we use the following (attached , it is a .sh file but I put .txt to be able to attache it):

$ROOTSYS/bin/root-config --features
