Link issue

[Adam Dershowitz-2]

I am not really sure if this is a Macports issue, a specific port  
issue, or something else entirely, but I figured I would ask here,  
because maybe someone can help.

I just upgraded to a new Mac and also upgraded from 10.5 to 10.6.  I  
did a reinstall of macports and my ports, as instructed on the  
migration page.  One of the ports that I re-installed is qt4-mac.
The problem is now when I try to build sqliteman (an application that  
uses qt4, but that doesn't yet have a port) I get a link error:

Linking CXX executable sqliteman
ld: library not found for -lcrt1.10.6.o
collect2: ld returned 1 exit status
make[2]: *** [sqliteman/sqliteman] Error 1
make[1]: *** [sqliteman/CMakeFiles/sqliteman.dir/all] Error 2
make: *** [all] Error 2

Now, I have found crt1.10.6.o in /usr/lib.  So it seems that something  
is wrong in my search paths.  I also tried doing this before my build:
export LIBRARY_PATH=/usr/lib:$LIBRARY_PATH

but I got the same error.  So it seems that for some reason some  
combination of cmake, make and ld are not searching in the correct  
location.  I was able to go back and look at my old machine and didn't  
see anything in PATH or LIBRARY_PATH about /usr/lib either, so I am  
not sure where this path should be indicated?  Is it set in an  
environment variable, in qt, in cmake, in macports?
Is something wrong with Macports, qt4, cmake, XCode (I did upgrade  
that to the newest as well), my .profile, something specific to  
sqliteman?

It clearly is something that recently changed, but that could be going  
to 10.6, or a new install of macports, or something else.  The one  
thing that did not change is that I am actually using the identical  
source code for sqliteman.

I am somewhat stumped, so figured I would ask.

Thanks for any suggestions,

I figured out the solution, and other people could run into it, so I  
figured I would pass it on.
It was not actually a macports problem.  But it seems that something  
from my old computer was being cached, even after doing make clean and  
a new cmake.   I found that going back to the original source code and  
then doing a cmake and make did the job.
My guess is that it was CMakeCache.txt that was not being regenerated.
Anyway, just a caution about odd link errors after upgrading from 10.5  
to 10.6.
