According to the log:

What is the output of the following?

port -v installed cfitsio

Did you change your supported arches in your macports.conf file?

[vincent.hbr@…]

Replying to macsforever2000@…:

What is the output of the following?

port -v installed cfitsio

The following ports are currently installed:
  cfitsio @3.280_1 (active) platform='darwin 10' archs='x86_64'

Did you change your supported arches in your macports.conf file?

I did not change the macports.conf file.

What version of Mac OS X and Xcode and you running?

[vincent.hbr@…]

Replying to macsforever2000@…:

What version of Mac OS X and Xcode and you running?

Mac OS X 10.6.6, Xcode 3.2.2

[ryandesign (Ryan Carsten Schmidt)]

Should be fixed by adding a dependency on cfitsio; done in r82133.

Also filed #30656 which may be related.

[vincent.hbr@…]

That doesn't seem to fix the problem. I get the same error after revision of the portfile.

Note that there is also still an error with libwcs: libwcs.a, file was built for unsupported file format which is not the architecture being linked (i386).

[ryandesign (Ryan Carsten Schmidt)]

Can you attach the new main.log?

I don't understand why montage is trying to build i386 for you when you appear to be on an x86_64 machine running Snow Leopard where things should be building x86_64. Can you explain this?

[vincent.hbr@…]

new log

[vincent.hbr@…]

I don't understand either why it tries to build i386. I am running Snow Leopard.

[ryandesign (Ryan Carsten Schmidt)]

What version of Xcode is installed?

[vincent.hbr@…]

Xcode 3.2.2, as mentioned above.

[ryandesign (Ryan Carsten Schmidt)]

And what is the output of:

cc -v

[vincent.hbr@…]

[ryandesign (Ryan Carsten Schmidt)]

That looks normal. Mine is build 5666 because I'm running Xcode 3.2.6; you might want to update just out of principle but it shouldn't affect the issue you're having.

Your computer is 64-bit capable yes? What's the output of:

sysctl hw.cpu64bit_capable

[vincent.hbr@…]

yes.

% sysctl hw.cpu64bit_capable
hw.cpu64bit_capable: 1

[ryandesign (Ryan Carsten Schmidt)]

I think I see the problem. What is the output of:

gcc -v

[vincent.hbr@…]

[ryandesign (Ryan Carsten Schmidt)]

Bingo. "gcc" is an old version of gcc, whereas "cc" is the correct version for Snow Leopard.

This would not have been a problem if the port had been UsingTheRightCompiler, as requested in #30656.

Have you deliberately selected this older gcc 4.0, perhaps using "port select gcc", or by manually setting the gcc symlink?

[vincent.hbr@…]

Great. I don't remember deliberately selecting gcc 4.0, but that was the problem. Montage now builds fine when using gcc 4.2. Thanks for the quick and efficient support!

[ryandesign (Ryan Carsten Schmidt)]

Glad we got that figured out. The real solution to prevent this from happening for other users who have changed their selected compiler will be to fix #30656.
