Comment(by glynn):

 Replying to [ticket:1943 hamish]:

 > AFAICT the LOC_CHECK_LIB_PATH() checks in configure.in doesn't actually
 do anything beyond print a message to the log saying:
 >  checking for location of Whatever library...

 It prints a message, checks that that the specified directories exist, and
 either adds appropriate -L switches to the variable specified by the third
 argument or (if any specified directory doesn't exist) generates an error.

 It doesn't check for the existence or validity of a specific library; it
 just validates the directories specified with the --with-<package>-libs=
 switch. It can't check the validity of a library, as the arguments don't
 include the actual link name of a library (the first argument specifies
 the name of the switch, the second argument is the name to be printed in
 the "Checking ...." message).

 Use LOC_CHECK_LIBS or LOC_CHECK_FUNC to check for the validity of
 particular libraries.
