Sure - instead of what you did, just add --without-portals to your original
configure. The exact option depends on what portals you have installed.
Here is the relevant part of the "./configure -h" output:
--with-portals=DIR Specify the installation directory of PORTALS
--with-portals-libs=LIBS
Libraries to link with for portals
--with-portals4(=DIR) Build Portals4 support, optionally adding
DIR/include, DIR/lib, and DIR/lib64 to the search
path for headers and libraries
--with-portals4-libdir=DIR
Search for Portals4 libraries in DIR
Just do --without-portals or --without-portals4 (you don't need the matching
libdir option), whichever matches what you have.
