gcc42 fails to build

How silly of me not to check the Portfile; sorry about that.  It  
built fine for me on an Intel Core Duo Macbook Pro, and apparently  
for others as well, which is why I assumed the problem was elsewhere.

One is supposed to be able to set at least some arguments on the  
command line like this:

port install gcc42 build.args="-j 1"

If that doesn't work, it actually shouldn't be that painful to edit  
the Portfile in your local tree; it should be in ${prefix}/var/db/ 
dports/sources/rsync.rsync.darwinports.org_dpupdate_dports/lang/gcc42/ 
Portfile, in which case you can just delete the build.args line.   
Note that it will be overwritten when you next run "port selfupdate"  
or "port sync", but it should be fine for testing whether or not  
removing the -j flag fixes the problem for you -- provided you have  
the time an patience to wait for it to build :-)

Now that I think about it further, there might be something else to  
try: without modifying build.args on the commandline or in the port  
file, try installing it, wait for it to fail, and then try it again  
straight away (make will try to pick up from where it left off).  I  
did that when I was mucking around with -j on another port, and that  
at least enabled the build to work.  It's not really a solution, but  
if it works, it's a workaround that should at least be faster than "- 
j 1".

Kind regards,
