PKG_CONFIG_PATH not working

[Vergil83]

as the title says, it is pointing to /usr/local/lib/pkg-config
however, when I try

PKG_CONFIG_PATH=/usr/lib/pkg-config

and/or

export PKG_CONFIG_PATH=/usr/lib/pkg-config

it still points to /usr/local/lib/pkg-config

It is a common problem (google search and lf search) but so far no solutions have worked.

slackware 10.1, 2.6.10

thanks in advance

well if this is needed all the time then set an 'enviromental varible'

what like this

PKG_CONFIG_PATH=/usr/lib/pkg-config:$PATH:$/usr/local/lib/pkg-config
