Gentoo devs have made gdbm, more and more, an optional package; I have had -gdbm in my global USE flags since sysinstall. Seeing that my current packages all made gdbm completely optional, I removed gdbm 1.8.3-r1. In apache-2.0.54-r13.ebuild, the USE=gdbm flag and gdbm DEPEND has been removed. But the apache build process inserts -lgdbm flags which error out the make when gdbm is not installed (please note my system uses MAKEOPTS=j2): /usr/share/apr-0/build/libtool --silent --mode=compile i586-pc-linux-gnu-gcc -pthread -O2 -mtune=k6-2 -pipe -DLINUX=2 -D_REENTRANT -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -D_SVID_SOURCE -D_GNU_SOURCE -DAP_HAVE_DESIGNATED_INITIALIZER -I/usr/include/apr-0 -I. -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/os/unix -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/server/mpm/worker -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/http -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/filters -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/proxy -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/include -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/generators -I/usr/include/openssl -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/dav/main -prefer-non-pic -static -c htdbm.c && touch htdbm.lo /usr/share/apr-0/build/libtool --silent --mode=link i586-pc-linux-gnu-gcc -pthread -O2 -mtune=k6-2 -pipe -DLINUX=2 -D_REENTRANT -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -D_SVID_SOURCE -D_GNU_SOURCE -DAP_HAVE_DESIGNATED_INITIALIZER -I/usr/include/apr-0 -I. -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/os/unix -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/server/mpm/worker -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/http -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/filters -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/proxy -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/include -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/generators -I/usr/include/openssl -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/dav/main -export-dynamic -L/usr/lib -o htpasswd htpasswd.lo -lz -lssl -lcrypto -ldl /var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/srclib/pcre/libpcre.la /usr/lib/libaprutil-0.la -lgdbm -ldb-4.2 -lexpat /usr/lib/libapr-0.la -lrt -lm -lcrypt -lnsl -lpthread -ldl /usr/share/apr-0/build/libtool --silent --mode=link i586-pc-linux-gnu-gcc -pthread -O2 -mtune=k6-2 -pipe -DLINUX=2 -D_REENTRANT -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -D_SVID_SOURCE -D_GNU_SOURCE -DAP_HAVE_DESIGNATED_INITIALIZER -I/usr/include/apr-0 -I. -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/os/unix -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/server/mpm/worker -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/http -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/filters -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/proxy -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/include -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/generators -I/usr/include/openssl -I/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/modules/dav/main -export-dynamic -L/usr/lib -o htdigest htdigest.lo -lz -lssl -lcrypto -ldl /var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/srclib/pcre/libpcre.la /usr/lib/libaprutil-0.la -lgdbm -ldb-4.2 -lexpat /usr/lib/libapr-0.la -lrt -lm -lcrypt -lnsl -lpthread -ldl /usr/lib/gcc/i586-pc-linux-gnu/3.4.4/../../../../i586-pc-linux-gnu/bin/ld: cannot find -lgdbm collect2: ld returned 1 exit status make[2]: *** [htpasswd] Error 1 make[2]: *** Waiting for unfinished jobs.... /usr/lib/gcc/i586-pc-linux-gnu/3.4.4/../../../../i586-pc-linux-gnu/bin/ld: cannot find -lgdbm collect2: ld returned 1 exit status make[2]: *** [htdigest] Error 1 make[2]: Leaving directory `/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/support' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/var/tmp/portage/apache-2.0.54-r13/work/httpd-2.0.54/support' make: *** [all-recursive] Error 1 Reproducible: Always Steps to Reproduce: 1. emerge -1 net-www/apache # 2.0.54-r13 Actual Results: ebuild exited with errors.

You should run revdep-rebuild if you have problems after unmerging a library. Re-emerge dev-libs/apr-util.
I did run 'revdep-rebuild -pv'. dev-libs/apr-util was not on the list (perl, apache and subversion were) as the system had the -gdbm USE flag set long before I removed gdbm. Apparently, some gdbm setup info was captured by apr-util regardless of the flag setting, which revdep-rebuild was not built to detect.
