Macports GCC 4.3 compilation error

[Paul van Hoven]

I try to install GCC43 on my OS X 10.6. When doing so I encounter the 
following error:

wlan-44-86:~ toom$ sudo port install gcc43
--->  Computing dependencies for gcc43
--->  Building gcc43
Error: Target org.macports.build returned: shell command failed (see log 
for details)
Log for gcc43 is at: 
/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_gcc43/main.log
Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>


So having a look into the main.log tells me
wlan-44-86:~ toom$ tail -n 100 
/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_gcc43/main.log

What do I have to do to repair this problem?
