Re: Installing Oracle Client 10g on FreeBSD

	The discussion here is about mixing native FreeBSD perl and Oracle Linux instant client libraries, not a general discussion about so-called "linux emulation" under FreeBSD.

	If someone knows how to mix them, then i'll be really thankful to him/her for the directions how to do it. General comments about interoperation of FreeBSD native code and Linux libraries to do solve the issue.
