Recently I ran into problems when installing OAuth PECL extension for XAMPP beta on Mac OS-X. Running pecl from the command line gave the following error:
bash-3.2$ /Applications/XAMPP/xamppfiles/bin/pecl Notice: unserialize(): Error at offset 250 of 1301 bytes in Config.php on line 1050 ERROR: The default config file is not a valid config file or is corrupted.
Luckily, the solution to this problem is pretty simple. First, delete pear.conf by making a backup in your XAMPP setup:
bash-3.2$ mv pear.conf pear.conf.backup
This way PECL will create a new and correct config file when running the command again. Obviously, XAMPP ships with a corrupt pear.conf.
Then, install the OAuth extension as usual:
bash-3.2$ sudo /Applications/XAMPP/xamppfiles/bin/pecl install oauth

Libraries have been installed in:
/private/tmp/pear/temp/pear-build-rootjw6ahH/oauth-1.2.3/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable
during execution
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
