igraph problem on Lion

[Wu Degang]

Hi,

I was trying to build igraph 0.5.4 on Lion but failed. The following is 
the error message in the terminal:

Error: Target org.macports.build returned: shell command failed (see log 
for details)
Error: Failed to install igraph
Log for igraph is at: 
/opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_ports_math_igraph/igraph/main.log

The following is the relevant (I think) section in the log file:

It looks like there is something wrong with the source file of igraph, 
but I am not sure.

Cheers,
