While configuring Fluxbox 0.9.12

checking whether to have Imlib2 (pixmap themes) support... yes
checking for imlib2-config... no
checking for imlib2 - version >= 1.0.0... no
*** The imlib2-config script installed by imlib2 could not be found
*** If imlib2 was installed in PREFIX, make sure PREFIX/bin is in
*** your path, or set the IMLIB2_CONFIG environment variable to the
*** full path to imlib2-config.
no

now if i go to rpmdrake it says i have
imlib
libimlib1

imlib2
imlib2_loaders
libimlib2_1
libimlib2_1-filters
libimlib2_1-loaders


Whats going wrong here?

System :
Mandrake 10
1686

check /usr/lib/pkgconfig/ and /usr/local/lib/pkgconfig/ for a file named "imlib2.pc"

look for the line that says prefix=...

add the PREFIX/bin directory to your PATH environment variable, e.g. if its says prefix=/usr/local, add /usr/local/bin to your path like:

export PATH=$PATH:/usr/local/bin

Do yo have imlib2 installed;

locate imlib2

fixed it by installing imlib2 from source
