Error running MacPorts

[Richard Connamacher]

I'm having a problem with MacPorts (though for all I know it may be  
gcc rather than MacPorts itself). After restoring my system from a  
crash, port now can't compile anything.

I've reinstalled MacPorts 1.5, and I've reinstalled XCode 2.4.1 (BSD  
Tools). Still no dice.

The error I'm getting is like this:

--------------------

MacG5:~ root# /opt/local/bin/port install jpeg
---> Configuring jpeg
Error: Target org.macports.configure returned: configure failure:  
shell command " cd "/opt/local/var/macports/build/ 
_opt_local_var_macports_sources_rsync.macports.org_release_ports_graphic 
s_jpeg/work/jpeg-6b" && ./configure --prefix=/opt/local --enable- 
shared --enable-static " returned error 1
Command output: checking for gcc... gcc
checking whether the C compiler (gcc -O2 -L/opt/local/lib) works... no
configure: error: installation or configuration problem: C compiler  
cannot create executables.

Error: Status 1 encountered during processing.

--------------------

To get the exact GCC error:

MacG5:~ root# gcc -O2 -L/opt/local/lib
powerpc-apple-darwin8-gcc-4.0.1: no input files

--------------------


Any ideas?

Thanks!
