.SH "NAME"
port-rev-upgrade \- Check for linking inconsistencies and attempt to fix them automatically\&.
.SH "SYNOPSIS"

\fBport\fR [\fB\-vdy\fR] \fBrev\-upgrade\fR

.fi
.SH "DESCRIPTION"
.sp
\fBport rev\-upgrade\fR will check all binaries (i\&.e\&., executables and libraries) installed by MacPorts for consistency\&. If any linking problems such as missing or incompatible libraries are found, \fBrev\-upgrade\fR will rebuild broken ports in an attempt to fix the problems\&.
.sp
By default, \fBrev\-upgrade\fR is run automatically after each installation or upgrade, unless you pass the \fB\-\-no\-rev\-upgrade\fR option or disable this beahvior in \fBmacports.conf\fR(5) using the \fBrevupgrade_autorun\fR switch\&.
.SH "OPTIONS"
.PP
\fB\-\-id\-loadcmd\-check\fR
.RS 4
Check the ID load command in each library installed by MacPorts\&. This load command contains a path that should always reference the library itself, because the path will be copied into all binaries and libraries that link against this library\&. This option verifies that this is the case and will detect incorrect or non\-absolute paths\&. Since this check is only helpful for port maintainers, it is disabled by default\&.

Please see the section \fBGLOBAL OPTIONS\fR in the \fBport\fR(1) man page for a description of global port options\&.
