Replying to my own question.
I resolved previously reported ldc2 error.
I removed distro (Ubuntu/Mint) version of ldc , and instead 
installed 1.16 from the
release page ( https://github.com/ldc-developers/ldc/releases ).

The compilation error is now gone.
I also created the 'activate' script to setup paths (it was not 
avaialble in the LDC tar)
in case is anyone interested it is attached below (just modify 
LDC2_ROOT variable)

$ cat dlang/ldc2-1.16.0-linux-x86_64/activate

# copied form dmd version of the script

deactivate() {
     export PATH="$_OLD_D_PATH"
     export LIBRARY_PATH="$_OLD_D_LIBRARY_PATH"
     export LD_LIBRARY_PATH="$_OLD_D_LD_LIBRARY_PATH"
     unset _OLD_D_LIBRARY_PATH
     unset _OLD_D_LD_LIBRARY_PATH
     unset DMD
     unset DC
     export PS1="$_OLD_D_PS1"
     unset _OLD_D_PATH
     unset _OLD_D_PS1
     unset -f deactivate
}

_OLD_D_PATH="${PATH:-}"
_OLD_D_LIBRARY_PATH="${LIBRARY_PATH:-}"
_OLD_D_LD_LIBRARY_PATH="${LD_LIBRARY_PATH:-}"

# modify this
export LDC2_ROOT=~/dlang/ldc2-1.16.0-linux-x86_64
export 
LIBRARY_PATH="${LDC2_ROOT}/lib${LIBRARY_PATH:+:}${LIBRARY_PATH:-}"
export 
LD_LIBRARY_PATH="${LDC2_ROOT}/lib${LD_LIBRARY_PATH:+:}${LD_LIBRARY_PATH:-}"
_OLD_D_PATH="${PATH:-}"
_OLD_D_PS1="${PS1:-}"
export PS1="(ldc2-1.16)${PS1:-}"
export PATH="${LDC2_ROOT}/bin${PATH:+:}${PATH:-}"
export DMD=ldmd2
export DC=ldc2
export DUB=dub
