 Hello,

 I am trying to install the gcc48 port but it keeps returning an error.  To
 that end I have tried to remove both gcc48 and apple-gcc40 and followed it
 with clean and have reinstalled both, but keep getting the same error:

 Also if it does build successfully, where will I find (location) the gcc
 executable?

 Thank you for your help,[[BR]]

 It's just a warning actually, not an error. This output is part of the
 "[wiki:SummerOfCode2011#rev-upgrade rev-upgrade]" feature of MacPorts,
 which, after you install or upgrade any port, checks every installed port
 to see if there are any linking errors. It's trying to locate and check OS
 X Mach-O binaries and libraries. In this case, rev-upgrade has identified
 this particular file crt3.o as a Mach-O file, but I'm guessing that in
 fact it isn't, and so it prints a warning saying it might be corrupt.
 That's probably fine and normal for this file. It might be nice to enhance
 the rev-upgrade feature so that it recognizes this type of file and skips
 over it instead of reporting it as corrupt, but I don't know what criteria
 would be used to differentiate this file from the Mach-O files that it
 does need to check. I'm Cc'ing Clemens who designed the rev-upgrade
 feature.

 This confirms there's no real problem. The gcc48 port is successfully
 installed.

 > Also if it does build successfully, where will I find (location) the gcc
 executable?

 `port contents gcc48` will show you what files were installed.
