Can't selfupdate -- libcurl present but not found

[Philip Hudson]

I have a persistent issue with MacPorts 1.5.0.

selfupdate to 1.520 fails on a MacBook Pro running OS X 10.4.10.  
Multiple reinstalls of MacPorts 1.5.0 have not solved it.

Incidentally, although I've moved all the directories named in the  
FAQ for uninstalling, I notice that the installer UI's last screen  
button text always says "Upgrade", not "Install", though the panel  
body text says "...perform a basic installation...".

Other MacPorts 1.5.0 installations on two PowerPC PowerBook G4s on  
the same LAN (one Titanium running 10.3.9, one Aluminum running  
10.4.10) managed to selfupdate to 1.520 correctly.

I guess it's unlikely that it's an Intel-only bug -- it would have  
been spotted long ago -- so I guess there's something wrong with  
where/how I have curl installed on the MBP.

Here's the error message:

Here's my curl locations and other relevant stuff:

I've googled the error message several times over the last month,  
hoping someone else might have had (and solved) the same problem, but  
without luck. I've scanned this lists archive, I've tried the verbose  
switch, I've turned off Little Snitch, I've read every word on the  
MacPorts wiki. Any ideas would be gratefully received.

TIA,
Phil
