[ptxdist] pkg-config-wrapper

[Richard OGrady]

Hello,

Debugging a prepare stage issue so trying to understand this chunk of code in 
pkg-config-wrapper.

for pkg in ${pkgs}; do
   if [[ ! " ${whitelist} " =~ " ${pkg} " && ! "${pkg}" =~ '-uninstalled' ]]; 
then
      echo "$(basename ${0}): warning: blocking '${pkg}': not selected by 
'${PKGCONFIG_WHITELIST_SRC}'" >&${ERROR_FD}
      exit 1
  fi
done

Where does ${whitelist} come from?  Have tried to trace this back and best 
guess is it may come from ../state/${PKGCONFIG_WHITELIST_SRC}. pkgconfig .

If this is the case, perhaps pkg-config-wrapper can't be used during prepare as 
the .pkgconfig file isn't there yet?
