[courier-users] problem with ./configure for courier-authlib-0.58 on openBSD 3.8

[Derek S. <de...@bi...>]

I have successfully configured, installed and tested authlib one time,
using a restricted configuration.  I now need to re-configure it for
production use, but I am running into a problem for which I can find no help

When I now run the configure script for courier-authlib-0.58, I get the
following output (and failure of the script):
     ./configure[25709]: .: conftest2.out: not found

conftest2.out *is* in the directory where I am running the configure
script.  Here are the file details
     $ ls -al conftest*                                              
     -rw-r--r--  1 bisi  bisi  277 May  2 08:34 conftest.out
     -rw-r--r--  1 bisi  bisi   61 May  2 08:34 conftest2.out

bisi is a regular user I am using to config and compile the programs
(per the instructions in courier-IMAP/INSTALL.html document).

This error occurs no matter what the ./configure options & variables are.

here's the original config command line (formatted to avoid word-wrap
issues)
$ ./configure --with-gnu-ld \
          --with-db=gdbm \
          --without-authpam \
          --without-authldap \
          --without-authvchkpw \
          --without-authshadow \
          --with-mailuser=courier \
          --with-mailgroup=courier

In order to get the program to configure the first time, I had to set
CPPFLAGS and LDFLAGS (since the OBSD package puts the gdbm libraries
outside the gcc search paths).  Here are the settings for those env vars:
CPPFLAGS=-I/usr/local/include
KSH_VERSION='@(#)PD KSH v5.2.14 99/07/13.2'
LDFLAGS=-L/usr/local/lib

I have also removed the source directory and started from scratch, with
no change in the results.  That is, I removed the courier-authlib-0.58
directory, and then untarred the source files from the tarball, and
re-ran the configure script

running the configure script as the superuser makes no difference

I have tried with both the default Korn shell, and Bash.

I have installed no other software since I first compiled authlib.  I
ran into this problem immediately after I finished testing authlib and
then tried to run the configure script with a less restrictive set of
options.

I have put a copy of the config.log at the address below, along with the
other 5 files created by the ./configure script, run without any options
or variable assignments.

Any guidance welcome!
