You can say that again.

I was trying to build postgresql83 with this command:
$ sudo /opt/local/bin/port -v install postgresql83 +universal  
configure.compiler=gcc-4.2 configure.optflags=-fast configure.m64=yes  
configure.march=nocona

The process hung (overnight) at run_tic.sh [1] which was related to  
ncurses dependancy, which is a dependancy of readline dependancy,  
which is a postgresql83 dependancy.


With help of -v verbose output and Rainer Müller's comment I decided  
to change two default values in
> ${prefix}/share/macports/Tcl/port1.0/portconfigure.tcl

for the compiler; "darwin 9" { set compiler gcc-4.2 }
and for the optflag; default configure.optflags {-fast}

-m64 doesn't seem needed to be specified, it was now often double in  
commands listed in the verbose output.

One command was decided to be kept on the port command line:  
configure.march=nocona.

Also when switching portconfigure.tcl back to gcc-4.0 / -O2
$ sudo /opt/local/bin/port -v install ncurses +universal
(universal=x86_64) hangs.

Uninstalling & cleaning: ncursesw & ncurses doesn't improve, ncurses  
still hangs at executing run_tic.sh [2]
