Readline fails to build (yet again)

[lists at mgreg.com]

Hi All,

I'm attempting to install several items that depend on "readline" -- a  
couple of which are "unixODBC" and "FreeTDS".  I'm getting the  
following errors during the process:

...
install: you may need to run ldconfig
Error: Target org.macports.destroot returned: no such file or directory
Warning: the following items did not execute (for readline):  
org.macports.activate org.macports.destroot org.macports.install
Error: The following dependencies failed to build: readline
Error: Status 1 encountered during processing.
...


I apologize in advance for the seemingly repetitive nature of my  
question (as it seems that folks are constantly having trouble with  
readline), but I'm completely stuck.  I have seen answers to similar  
issues, but nothing is working.  I've sync'ed, updated, upgraded, etc  
and nothing seems to fix it.

Although the errors seem rather straightforward, I'm not clear on how  
to proceed.  I've googled each line individually and none of the  
encountered "fixes" addressed this particular issue. Thoughts?


Much appreciated,
Michael
