Most likely your libhdf.la has -L/usr/libs in its dependency_libs entry.  You 
can fix that by editing the libhdf.la file to pass the library name by its full 
path, or by adjusting the install process of libhdf not to record -L/usr/libs 
there.

I hope you don't mind that I read this email that you didn't address to me, and 
then replied to it on a public mailing list ;)  But then you already violated 
the supposed confidentiality of the message by displaying it in public, and 
allowing it to be archived forever by the GNU list archive and various mirrors.

But seriously, it is pointless and counterproductive to put such disclaimers on 
email that you distribute via a public list.  Please don't do that.  If your 
company's mail gateway appends that text, you should simply send your public 
postings through a gmail SMTP server or similar.
